Guys,

Does anyone know -- if you have to replace the ECM harness.. do you have to go all the way through the firewall or is there a plug on the inside of the firewall?

My harness that goes to my ECM needs to be replaced for reasons I mentioned earlier, and it's a very expensive job they say they have to go through the firewall. One would think on a newer car there would be a plug inside the firewall so you could easily replace that harness.

Is it wired to anything else behind the dash ? Or is it just two plugs? One plug to ECM and one plug to firewall plug (or engine plug, whatever)

Any diagrams would be appreciated, too, if anyone has.

Thanks in advance,

Hmm.. wow, thanks. They are telling me they need to go all the way through the firewall and it's a ten hour job, just to replace the ecm harness. (The wires close to the connector to the ECM and the plug that goes into the ECM are a little butchered) ..

Sounds like NOT a 10 hour job (and they said $675 for parts)

thanks,

Even when I check online, the harness is like $600.

Why so expensive? It's just a 10-foot bundle of wires with a plug on each end, right??

Regards to the price,

Remember you are dealing with import parts plus
mark up and also how often does someone have to replace a main harness like you???sorry!!!

 

hey. can i buy your defective harness off you?
Gforce needs it

dude, if and when we do this job yes you can. I don't even think it's defective, just poked into with a wire tester. just needs some electrical tape in my opinion..
