Thanks for the 'welcomes'.


Jason, I can't make this Saturday but might be able to in the future.


As for the wiring pictures in your post.....the connectors shown were from the donor car, you added the wires from one end to the other. You have a connector for the DIC, one from the back that goes to the DIC and the other connects the DIC to the existing wires in the rear?


Is that about it? am I missing anything? Or, correct me if I'm off base.


Thanks.

Welcome to the forum!

 

I did not add any wires. When you pull the roof wiring harness, you take from the wires that are used in the connector for the DIC and go all the way to the fat connector in the back (everything else is expendable, just don't cut any DIC wires). When you get to the connector in the back, you will need both the female and male parts of that connector. Any wires not part of the DIC wires that you pulled front to back, trim a few extra inches inches on both sides (gives you something to splice back together).

It's really easy when you start ripping into it. Be prepared, to get access to the connector in the back, I had to take the entire rear seat out and one side of the upper rear quarter trim and the speaker deck.

 

I know I need to see this first hand before I truly understand...but....is the donor wiring harness a direct plug in then?

 

Almost. If you look at the first 3 pics in my thread about it, the first shows the entire wiring harness I pulled from the roof of a donor car. The second shows the harness after I pulled all the tape off and separated the strands I need from the remaining wires I did not need (isolating just the DIC wires to the big rear harness). The last pic shows the soldering I had to do to make the T for the T harness. Had to bridge the wires that are not used for the DIC so when I put this harness inbetween the connector in the rear passenger side quarter the other connections that pass through that connector not used for the DIC still work. Once I finished I wrapped it all in electrical tape much like the factory did.
After that it's a simple plug and play. This allows you to add the DIC without dropping the entire headliner (just tuck the wiring up in the headliner).

Your only other option would have would be pull the entire donor roof wiring harness, drop you headliner down, remove your roof wiring harness and install the donor one. I feel this is more time consuming, pain in the butt and high potential to break something. Plus gm glues the harness to the headliner.

 

so the only wiring you took from the donor car was the roof wiring harness the other connectors are already a part of the existing wiring is that right?
