Maybe I missed it but why not just swap the entire engine side harness from the donor to add in the trans wiring?

Donor had a 454, and my truck has a 350, so I just assumed it would be different.

In a previous life I used to be tasked with hot-rodding our older military fighters with new/improved Avionics systems. And the first jet was always a crazy challenge, and took way longer than it was supposed to. But as we went through the fleet, we would take the lessons learned & also get really familiar with the relevant wiring diagrams...so that by the end of our fleet we would actually take less time than documented and be able to make all the changes and have the follow-on Ops Checks pass with no wiring harness troubleshooting.

When I was a dealer tech we called that "gettin' a zipper on it". The first time you did it, it took forever. After a few times you had the job down to where you could just "unzip it, install the part, and zip it back".

Gone and done it...

Cut holes in my new headliner, for the overhead console, that I took out of the parts truck.

I still have to take it back out, and either rewrap the trim in black headliner, or if it will clean up good enough, I'm thinking of painting SEM satin black like the rest of the plastics.

When I took the console out of the parts truck, I grabbed the harness too, since the dash was out of the way, and made this a 99% plug and play operation.

The console harness, and roof light harness use the same plugs, in the main harness under the dash.

The two circled plugs run the roof light/over head console. The gray plug has two pins, but only one is used for either item. I de-pinned the console harness, and put it into the empty spot of the roof light harness. The ground plug only has one spot, so that's the 1% that wasn't plug and play. Simple splice, and it was ready to rock.

Bet that was a stressful job :[] looks good though.

Will it come apart enough to wrap the tan portion in headliner material then paint the dark grey to match?

I was sweating that first cut.
Yeah, the trim comes off the main part. Looks like it'll be pretty easy to work with.

Much better...

Getting all the old adhesive was a chore, but it slicked up pretty good. I still might wrap the trim piece later, if I can find a material, that's a good match to the seats, but for now I like the SEM Satin Black.

Man that’s slick. I’m about ready for a color change in mine…

 

[Stumpy]

Ordered some LEDs, and got them today.

Slid right in that tight spot, without modding anything.

That looks great! Nice job!!

Looks like it grew there, as we say.
