#126828, "Adding an ECU Harness.."




          

My 95 keeps eating up ECUs left and right. Also, Ive heard around that 95 is the worst of all the 2gnt ECUs, and that they got somewhat better each year. I bought that $300 RS, which was a 98. I was wondering how plausible it would be to cut the ECU harness out say 8-12 inches from the connector, and connect it to my existing ECU wires. This way, I can test to see how my car would handle a 98 ECU, while still having the 95 connector in case I want to go back to it, or for emissions or whatever. Only one ECU would be connected at a time, the other would just be an empty harness.

You will need to look at the pinouts for both.

There would definitely be a few wires with no place, or for which the 95 ECU doesnt control.

It could work, just take alot of time and careful research.

I probably would not invest the time, and swap the whole harness to 98. As long as there are no codes, I dont think the emissions place will care.

IIRC some of the sensors don't read the same either. Didn't someone post a while back that 97+ cam sensors didn't work with the 95 ECU or something like that?

This could have been years ago for all I know.

I think its only the connector.

I know that the connectors are different, maybe that's all that's the issue. I honestly can't remember.

Swap the entire harness and sensors.
