Edit: Figured it out. Order placed. Psyched to get this harness all made up - bonus is I can use it as a boomslang too - you guys are AWESOME for sharing so much info and I owe all of you a beer at NG

Did you buy the parts from the links a posted?
Yes, but I'm also using parts from a hacked 1g harness I have.Quote:

To make an adapter harness between a 1g and a hybrid ECU, the only thing you have to worry about is the little 12-pin plug. The other three plugs are for all intensive purposes directly complimentary.
See http://www.plxdevices.com/ECUDatabas...thTT_91_97.pdf.
Only 1 pin *needs* to go into the hyrid's 12-pin plug:
A quick run-through of the terminals off Stealth316 shows these pins are all in the 12-pin plug on the 94-95, and here's where they get their signal from on the 91-93:
Pin 59: A/C Switch 2
Pin 60: Rear heated o2 sensor, emissions (cali) - not present in 91-93
Pin 58: Engine Ignition Signal
Pin 52: Ignition Timing Adjustment Terminal
And come from these pins on the 91-93:
Pin 20: A/C Switch 2
Pin 101: Engine Ignition Signal
Pin 104: Ignition Timing Adjustment Terminal
In other words, if you want to run a 1g ECU on a 94-95, or a hybrid ECU in a 1g, you'll pretty much only have to deal with the Engine Ignition Signal and the 12-pin plug. SO there's no need to build a fancy adaptor harness unless you want to use it as a boomslang harness or something along those lines.
Thanks Corey!
What about an obd2 com port? This is important for 1G cars to use the evoscan 2.0 cable.
Don't quote on this but the DSM guys grounded pin 79 on to a 2.5mm aux port to allow the rewriting to the ECU. I don't see why we can use a similar method.
The com port is the missing piece of the puzzle ... I know you can wire one in, Aaron did it, but I don't know where to source the part. I suppose I could hit up the junk yard and hack one from a 2g DSM.
You can buy the flash connector dirt cheap. Here is the linkQuote:

You still need the 2.0 cable. All that piece does is provide a regulated power source to the cable which will enable flashing.Quote:
