I've decided it's time that I move my PCM into a better place inside the car instead of having it sitting on my floor by the passenger's feet (that's as far as it will reach right now and I don't want it under the hood). I don't see that Painless sells an extension, does anyone else? I don't want to splice every single wire at this point so just an extension that will hook right into the OEM PCM connectors and move the PCM back 3-4ft, and I can hide the connectors behind the kick panel.

 

If nobody makes one, thats a great idea, im sure there are Hundreds of people on this site alone that would want that.

 

Issues in making an extension is procurring the female PCM plug. In the factory application it is a header, not a connector like the wiring harness side.

Another option would be changing the connector all together, but that would still require, cutting and crimping all new terminals on the wires. Also, adding one more plug in line, creates one more spot for a bad crimp or failure point. For what its worth.

Taking with Wait for Me Tune, they said that significantly lengthening the harness to the ECU can change some of the sensitive sensor signals due to the additional resistance of the longer wires.

Makes sense, but you see guys like Painless selling super long harnesses for $1000 so maybe its not an issue?

 

I extended a harness for a Toyota pickup around 5' and put the computer under the back seat. Been running just fine for 3 years now. I would solder the connections though, crimps would not be my first choice for PCM wires.

 

well buy a break out box that will give you the right ends $$$$
