Sat radio module unplugged

[Amack1970]

So I started stripping my 10 cobalt today. After unplugging the module on the package tray the car wouldnt start? I have it partially plugged in now and it runs. Is there a fix to this, or do I have to keep this module on the goblin?

It won't run because the GMLAN data wires daisy chain through it. When you cut that module out, you basically hook the data wire ends together.

Is there instructions to bypassing it provided? Or is there a thread somewhere?

They run from OBD to power steering to BCM then to ECM. Really the only thing you do is extend them from the BCM to the ECM.

There is a ton of threads about these wires. The build videos also talk about them. Here is a diagram

Yep, as you follow the thinning of the harness videos, it will talk about it. It's fairly easy and when you get to that point, if you have any questions, we can help.

Thanks guys! The harness thinning is my only worry about this whole build. So some help would be great

When you go cutting, make sure you leave enough wire sticking out so you can solder another wire on if you screw up.

I think most people look back at the harness and say that it's really not that bad.

Get yourself access to Alldata or Chiltons for wiring diagrams. there are differences between the years and models. Follow the videos! I think that between all of us on here we have covered all of them. But it has been a while since some of us have cut it up and have to think hard about it. I recommend keeping Radio key and battery hot wires and one or two more for stuff you add in the future.
