    crank sensor in the distributor

    Ok guys, I know a few of you do the ecu swaps, so i need some info. 94-95 distributors have both cam and crank sensors, and 96-98 have only cam sensor in the distibutor - the crank sensor is next to the crank pulley.

    So my question is: Which pin on 94-95 distributor is the crank sensor signal? Any pinout diagram of that year distributor?

    Any help will be greatly appreciated!

    Crap I'll have to go outside and check when it's light out. It's either a brown/red or brown /green . (I know lol didn't help much)

    Please do, I need this asap! do you know if the other pins are the same for the two distributors, and to be more specific - cam sensor pin?



    Ok heres the idea!

    There were a few thread about difference in distributors, and if my memory serves me well, some1 said that 94-95 and 96-98 distributors are not compatible. Well maybe they are!!??

    This is what 2G guys do when they have bad crank position sensor - they swap with 1g cam position sensor that has both cam and crank sensors, and rewire it this way. Im pretty sure 94-95 distributor if functioning the same way



    Ok, 96-98 Galants use the same crank sensor as 2g, and it has very simple wiring diagram - power, ground and signal pins. There will be no problem taping into the distributor harness to get the power and ground, but I need need the pin of the crank signal on the distibutor.

    All this is about converting to OBD2 emission free harness that I have already, but I didnt wanna play with installin crankshaft plate /allocator/ and additional crank sensor

    ^^^Great info man! Thank you!

    I just need the pin color or number on top of the distributor

    All the below information is specific to a 95 SOHC Galant. The information was gathered from Mitchell Repair.

    The crankshaft position sensor wire is Brown/Green and the camshaft position wire is Brown/Red.

    The Brown/Red wire to the camshaft position sensor runs to pin 68 at the ecu which is labeled as the camshaft position sensor.

    The Brown/Green to the crankshaft position sensor runs to pin 69 at the ecu which is labeled as the coolant temperature sensor, but I believe this to be Mitchell's error and that it is the crankshaft position sensor.

    There should be a 6 pin connector on the distributor.
    Pin 1 = Black wire; ground; splices with several other wires that go to pin 26 at the ecu.
    Pin 2 = Black/White wire; power; splices with several other wires that go to fuel injectors, solenoids, o2 sensors, etc.
    Pin 3 = Brown/Green wire; crankshaft position sensor to pin 69 at the ecu.
    Pin 4 = Brown/Red wire; camshaft position sensor to pin 68 at the ecu.
    Pin 5 = Black wire; ground; splices with several other wires that go to pin 26 at the ecu.
    Pin 6 = White wire; ignition; power transitor wire to pin 10 at the ecu.

    There is a 2 pin connector on the distributor as well. The Black/White wire goes to the MPI relay pin 7 and 8. The Black/Yellow wire goes to the tachometer and a capacitor.

    Unfortunately the diagrams below are difficult to read because of the picture size limits, but I can email a larger copy of it if you want me to. Let me know.

    I hope this information helps you out. Good luck; let us know how you make out.

    Thanks,

    Mike

    i would jsut identify the pin on the ecu. then note the wire color combination, then find that color wire on your distributor harness. done.

    Thanks a lot guys! I really appreciated!

    Now I can get the OBD2 conversion done really quick

    if this is the pinout of 94-95 Galant distributor

    Pin 1 = Black wire; ground; splices with several other wires that go to pin 26 at the ecu.
    Pin 2 = Black/White wire; power; splices with several other wires that go to fuel injectors, solenoids, o2 sensors, etc.
    Pin 3 = Brown/Green wire; crankshaft position sensor to pin 69 at the ecu.
    Pin 4 = Brown/Red wire; camshaft position sensor to pin 68 at the ecu.
    Pin 5 = Black wire; ground; splices with several other wires that go to pin 26 at the ecu.
    Pin 6 = White wire; ignition; power transitor wire to pin 10 at the ecu.



    What is the pinout of the 96-98 galant Distributor without crank sensor. thanks

    So help me clarify which ecu you're goping with. i'm assuming 2g turbo ecu. and you have aobd2 wire harness, and you're putting it in your obd1 94 G.
    Why don't you just get the distributor that matches the wire harness you have?

    but for the information you are requesting, this is the information i have.

    You're Crankshaft position sensor is pin 2 - red/yel and runs to pin 69 on 7g OBD2 ecu / 89 on 2g ecu (which are actually in the same location they just numbered it different)
    you're Camshaft position sensor is pin 3 - brn/grn and runs to pin 68 on 7g OBD2 ecu / 88 on 26 ecu (same as a bove)


    So with the instruction above you would need to connect the brwn/red from the connector on the 94 distributor to to the red/yel that runs to the ecu.

    or, for a slightly cleaner / factory look.

    Use the original distributor harness and re pin using your existing wires.
    you could terminate the +/- for the crank sensor

    BUT
    if you are trying to apply the diagram the eclipse guys use to put a 1g crank sensor in their 2g there are a lot of other variables that might come into play.

    For example;
    The 1g CAS sends a signal to the ecu that is 180o out of phase with the 2g signal so you have to compensate
    They do so by change ing the pin locations of the injector triggers... 1 is 14 / 2 is 1 / 15 is 2 and 14 is 15
    They also change the plugs around 1 and 4 with 2 and 3 (order is not important)

    I got this info from Magnus Motorsport 1g in a 2g. you might look it up.

    I'm only telling you this part for just in case you get the wiring done and it doesn't start

    yes, i understand that. I gave the picture as a example for the 94 distributor having both cam and crank sensors just like 1G CPS.

    What Im trying to do is to rewire the 98 obd2 harness to work with 94 distributor
