^oh ok my bad... hopefully we got this fixed... i've been looking at the wiring and diagrams, and for the life of me, it all points to 3 and 4.... so idk...
ok, I worked on this a few times and here's where I am at right now.

I was reviewing the wire diagram sheet and looked for distinct wires that are only on one side (to distinguish a reference where pin 1 is, thus located 3 and 4 afterwards).

I used wire 8 as a reference; it's the wire for the engine coolant gauge. The color is Black and Red.

Looking at the harness (C-17) you find the one location for pin 8.

Using the diagram, and seeing pin 8 is the same side as pins 1 and 2.

(The other two wires on my finger are pins 1 and 2 according to the diagram, Red/Blue and Black/White. I've wired it to those wires and the speedo didn't work.)
You would determine pins 3 and 4 on the other side of the harness, which the next picture shows, at least for my harness and diagram.

My pin 3 is Yellow/Black and my pin 4 is Gray/Silver, this was the same two wires that worked for the speedo when I drove to Florida, but unfortunately for some reason I've wired the same setup back and it does not work. This is why I mentioned I might have to disconnect the battery and reconnect, just to double check cuz that's what i did last time before it started working again.
One thing confusing me is the wires at the actual sensor are the same wire in the diagram, yet viewing the same wires on the harness you see different colors.
(Pins 3 and 4 in the diagram are Yellow/Black and Black/Blue respectively, yet pins 3 and 4 on the harness are Yellow/Black and Gray/Silver :orangeno: )
I'm gonna try to continue working on this after work tomorrow but this is where i'm at thus far.
Any update on this? Are you already able to fix this? Thanks
I left my current wires connected and it works (unless i'm over 3/4 tank full then the speedo spikes). I'm gonna try to review the diagrams over the weekend and find out which wire i'm supposed to wire to. I just never fill over 3/4 so my speedo's been working the whole time. :lol:
will let you and WhiteGalant know the details....
Hey if anybody wants to work on the tranny speed sensor wiring my car is just sitting there waiting for some help.lol Im prob going to have the same problem cuz I have a 2002 Galant. Roman or Brian anybody that could help me out wire up the tranny to my car that would be awesome, and maybe get some answers here.
This is good. Lets get to the bottom of this. This is good info for future 5 speed conversion. I know by experience when you start messing with wires sometimes there are space for a fuse to blow up. Always check fuse after you change or try to re-wire.
If I ever get some free time I might take the drive out to help you with this Drew, this way we can put a nail in this coffin and save everyone else the trouble
Sounds good. I bet you will get it working. If you need any diagram let me know.
Already have diagrams, I have to see Stewi's diagrams to see if they're different from mine.
Thanks guys! I will try to rewire my speedo soon too next Sat as will swap the tranny at that time. Please keep us posted.
all right so this is starting to bug me no speedo... which kinda sucks... and no oddometer which is awesome.. lol needless to say i wanna get it fixed... so i started looking and read from another thread that there has to be wires there that can feed the signal all the way up to the cluster.... so i was thinking the a/t using two sensors, basically to see the torque slippage? between the input and output shaft... so if under normal driving with the 5 speed, do you think we could some how wire the speed sensor to the Two wires of the TWO different sensors to the one wire output signal of the 5 speed speed sensor..... so that it will send it to the pcm, and then to the cluster? or has this already been tried?

If the idea you have is correct that the input/output shaft speed signals would in fact get the vehicle speed to the ECU then to the cluster, this is what I would do. I would wire the signal from the speed sensor on the 5 speed tranny to the output shaft signal wire.
that makes sense... pin 3 is the power wire correct? and pin 2 is the signal? pin one is the chassis ground i'm assuming...
I cant remember off the top of my head. I dont have the diagrams on this PC so I cant check now.
alright so i attempted this today.... hooked it up and nothing... then i swapped 2 wires on the speed sensor itself, just incase i mixed them up, still NOTHING! lol i'm beginning to think i have a bad speed sensor... if you hooked up the wires wrong on the speed sensor, you could fry it correct? i'm beginning to think thats what happened. OR maybe you have to hook up both the input and output signal wires on the harness to the 3 wires on the speed sensor... that i did not try... any suggestions?
anybody? Bueller? Bueller? What was that? Nobody? lol
i'm gonna try to wire my sensor later.. i hope it will work following run's method. I don't mind it working under 3/4 fuel tank for as long as I have a speedo.
I was able to wire up my speedo 2 days ago. The Yellow wire from the speed sensor is the ground (connected to the battery), the White goes to the
Grey/Silver on the C17 connector and the Black goes to the Black/Yellow. My tank was half full at the time. I will try to get a full tank of gas and see if I will have the same problem run1206 had.
I hope this helps bro since we have the same wire colors from the speed sensor.
That sounds like the same color as the wires on my speed sensor, might give this a shot tonight.
Ok galante I tried what you did and still no luck. The only thing I did differenty was ground to the transmission and not the battery.
Grounding either to the transmission or battery should be fine. Try changing the sensor, it could be busted. The speedo was sloppy at first but it's normal now after driving for couple of minutes (same as what run1206 experienced).
Hmm guess Ill do that next.
so uuuuum i may have missed the solution to this but any updates?
Sorry I haven't posted in a while here. I left my speedo the same and haven't filled the gas tank all the way. Ill send stewi my diagrams to see if my wiring is messed up somewhere; I know one of the wires are hooked to one of the voltage signals to the gas somehow. Just gotta figure out which one. Will try other wire combos this week or next week.

ok here is a thought, are the engine harness the same across the years? except for the speed sensor connector, in the 02 and 03 its not there, cuz they went to VSS system... so can't we just swap the engine harness? and that should totally fix the speedo problem correct?
gotta check if the ECU will read the signals the same across different harnesses
well i guess if you have the sensor sending info across the wire to the ecu and its the same path, via correct pins, it should all work, the wire won't change your signal persay, its just a route for your sensors readings to get there... the only thing that i'm curious about is the 99 to 01 they use a speed sensor correct? where as the 02 to 03 used the vss so if its still the same sign wave signal or square wave, well whatever signal it is, and its the same against all years, it should work. hmm..
VSS stands for vehicle speed sensor. The 99-01 use the external removable sensor, the 02-03's use an internal sensor. How the internal sensor reads the speed is unknown to me, it may read off the differential (like the 99-01) or it may use an input shaft speed and output shaft speed sensor and do some sort of math equation to figure out the vehicle speed. If it is a math equation, where does it take place? Im gonna guess inside the ETACS ECU under the dash. I know you can throw a 02-03 cluster in a 99 and have no problems and vice versa, so its not in the cluster. I wish I had access to a 02-03 car so I could just go to town with a multimeter and figure this shit out.
^ i know on my tranny i had to sensors for the vss, one on the input and one on the output, how do i know this? its says in the manual that i downloaded, and i think its a magnetic pulse detection sensor, meaning that there is a magnet in the tranny itself, one on the input, and one on the output, and everytime it goes around it senses it and creates a pulse. well what i don't understand is why did they change it up? what is the benifit of have the computer calculate the speed? compared to just the removable sensor? what i do know cuz i have tried it is that you cannot hook up the speed sensor to the output speed sensor harness, and expect it to work. but then again i could have a bad speed sensor. But if you swap the harness to a 99 01 then you will need the ecu to go along with it is what your saying since it does the math inside the ecu. unless its the same math, just a different way of measuring to get the signal, but if you have 2 signals going to the 02 03 ecu and only one going to the 01 99, then just swaping the harness won't help, cuz your still missing a signal, so its not going to calculate the right speed. unless it is actually calculating the speed in the automatice tranny ecu, i forgot what its called, the powertrain something lol. i wish i had better schematics to tell you what voltage the signal was. ok question, if you swap the evo ecu, the 02 03 guys still would have to tap into the c17 harness to get the speed sensor to work correct?
I'm going to use alldata to find the VSS on the 02-03 galant. Let see where the sensor goes. I checked that the Vehicle Speed Sensor ( VSS ) is located on top right front of transaxle housing. it seems there are two sensors working together to make the speedometer to work the other sensor is trans main shaft speed sensor. Just throwing ideas here.
That all makes sense. That magnetic pulse sensor is also called a Hall Effect Sensor. Its the same style as the cam and crank sensors, sending a "pulse". The 99-01 VSS sensor im pretty sure sends just a voltage reading, im not sure if it uses that voltage reading and compares it to any other tranny sensor outputs to establish speed, I would imagine it doesnt since I have a standalone in my car and my VSS works just like normal. Im gonna see if I can read my VSS voltage thru the standalone and compare it to voltage at the cluster, im almost positive its gonna be the same.
Ok I just went diving thru my wiring diagrams and im ready to scream.
Can someone with an 02-03 check connector C17 and tell me the pin location of the white wire with the blue stripe and can someone pull their gauge cluster out and find the white wire with the blue stripe and give me the pin location for that one as well. Im gonna figure this shit out, I swear I am.
Alright so the ECU in the 02-03 does a math calculation to determine the vehicle speed, the ECU sends the speed signal to the cluster expressed as voltage. Im guessing its gonna be your typical 0-5v signal.
ok so i went out and took some pics also. but pin 16 and pin 34 on the male side of c-17 are blue with a white stripe. i didn't see any other blue/white stripe wires at all, not even on the cluster connectors.. but here are a couple pics
