yeah that wiring diagram is a pain to obtain. we might have to use your resources Blackheart.
Becuase the Diamante TB is different, as well as the IAC sensor plug you will neede to obtain a wiring schematic for the Diamante TB stuff. I was going to perform the Diamante Intake manifold and TB swap for my V6, but given the sensor differencse, and the minimal 3mm gain in size over stock I did not pursue the details further.
Ivory8g now has my Diamante TB and we are both trying to obtain the needed information in order to be certain the IAC pigtails are wired up correctly, unless others have the information available at this time...

Keeps us posted that's something Im interested in learning.
did a lot of reading on c3g and i might just balls to the wall and try something....

why is everyone having issues with idle? are you guys letting it warm up at all when testing? Cuz mine goes up to 2300 then drops to 800 (normal idle) after about 3-5 mins. and nothing but responsiveness while driving. IDK why you guys are having issues. Did you guys clean it beforehand? Adrian did clean the TB I got before shipping it to me so maybe thats causing an issue. but mine is fine as long as I let it warm up...
just so you know,
during my swap I ended up having to use the 6G74 IAC and the corresponding plug for it. I ended up just snipping off the old 6G72 plug (on the car's side of the harness) and wiring up the 6G74 plug (car side of the diamante) that came with my engine by matching up the pins. No codes or anything and I passed SMOG. I dunno if that answers your question or not
thats really what I was talking about when I was saying im just going to balls to the wall and just do it. i am gonna snip the harness and wire it in by the pin. its what the 3g guys seem to have done because they said the wires were all the same just different connectors. only thing is i take everything from that place with a grain of salt. so thats why i was waiting on the wiring schematics. did you use your stock tps or wire in the diamante tps according to the pins as well?

I used the Diamante TPS. It plugged right into the car's harness
also, the couple minutes of higher idling was and still is normal for me

beat me to but proved you have to have the V6 IAC for this swap to work on the I4, 4g63lover might want to update that to your tut, otherwise it's a great resource

I just cut off the old pigtail wire by wire, and soldered the new one for the 6G74 in the corresponding wire locations and everything works perfect. It was 6 wires in total. IMO, it was worth the 15 minutes it took to change the plug. Plus the TPS plug was a direct fit and everything is fully operational.

Never thought it would be as easy as just swapping the pins out. I just never found the benefit and time worth while for a small 3mm bore size gain over the stock TB for the V6 platform. The only thing I can justify being "worthy" of claiming a big bore TB swap for us would be jumping on a Q45 90mm TB unit. The 4 cyl folks are truely the ones who benefit from the Diamante TB though...
Should be interesting to see how it improves your low-mid end area with that beefy thing on there!
yes it shall! too bad i cant start my car cause my coilpacks are dead! :( I'll take it to my thread...

I became insane, with long intervals of horrible sanity.
mmm did you reset your ecu after puting in the new iac? like with anything doing with air modification's you should always reset your ECU so it can "relearn" the A/F ratio, did you get your iac from the junkyard, could it be bad? it's been raining cats and dogs here in texas so havn't gotten out to junk yards yet to get one, i know where there is one and the car is complete with a sealed hood so the one i get should be good gonna try to get out there tommorow if the weather is good i'll let you know if i run in to the same problem
I got mine from a junk motor at work. The IAC is fine. How do I reset the ECU? With a scan tool or just pull the negative terminal?? BTW my car has been DRINKING gas since this mod.

haha its not the car bro its you. lol.
On the serious, my gas mileage got better on the highway cuz RPM sits at 2700 instead of 3000 at 70mph. I havent driven in the city much to tell a difference there. And quite honestly, I am having trouble keeping my foot out of it cuz I LOVEEEE the exhaust note now! I feel like I'm sixteen again!!! (Wow, that sounded really effin' gheyyyy)
