Help: Looking for Patch harness or female connector for Atom 2 ECU

**2/3rdsCobra** · March 17, 2018, 03:53 PM

Ace Performance checked and couldn't locate a patch harness for the ECU (I'm going to run a Link G4+ Fury PCM in place of the P12 OE ECU). Does anyone here know where I can secure a patch harness or the female connectors (like the connectors on the ECU) for the Ecotec ECU? Any assistance or a point in the general direction would be appreciated.

Didn't Ace already make this conversion on another Atom 2?

Yep, a few but ALL were wire ins. I really don't want to go this route. A patch harness using a female plug (the part that is attached to the OEM ECU) is all I need. Ace can do the pin-outs.

It sounds like you want a plug-in solution so you don't have to butcher the OEM Atom 2 harness. I would try asking this in a Chevy Cobalt forum.

If you can't find what you need, you may be able to remove the connector you need from a Cobalt ECU and make your own adapter harness.

I'm thinking the same thing. Great minds think alike. I just hope I can remove the plug from the ECU if I can find another source.

A company named boomslang made one for my 300zx. I see they make them for vettes but not the cobalt. Might want to see if it's something they might tackle or at least have some insight on where to find parts.

Again, great minds think alike but no joy

I just looked in the GM parts catalog, and the three connector bodies for the LSJ PCM do not show a mating connector part number. That tells me that the only termination this connector was designed by GM for was at an ECU/PCM.

That's kinda what I figured. So, I am actually cutting the OE engine harness connectors to the ECU and completely repining each of the wires to the Link ECU connectors. I'm also attaching new sensors to the engine that will give the Link more info. Getting really excited for the upgrades.
