Hard to believe it's been this long to post again.
After the last post I installed a new wiring harness and sorted that out. Uncle Lucas took the wind out of my sails. I had to make up my own interconnect diagram as the S2 diagram only shows half of what you need. When I get this done I will post the diagram. Maybe it will help some other poor soul. Everything seamed to be working except the horns and the flash to pass function. The flash to pass works but does some strange things to the running lights. I have disconnected it as I will never use it. I added the ground wire to the steering u-joint but the horn button still doesn't work. I stopped working on the car for the 2017 holiday season. After that, I had some home projects that needed to be done. I got back to working on the car at the start of this year. I decided to work on the interior and give myself a break from electrical issues.
I had to install new windshield pillar trim pieces as the old ones were too brittle to use. I used an undersized hole saw the add the vent holes to the trim pieces. Then I used a small sanding drum the enlarge the hole to the proper size. It was when I went to install the trim that I discovered the windshield had to come out. After cursing my stupidity, I took the windshield out, installed the trim pieces and reinstalled the windshield. I had to bevel the trim flanges to get them to fit under the gasket, but the fit pretty well.
I found that using a paint can opener worked well to pull the gasket over the trim in some spots.
I took the vents apart and clean them and painted the aluminum. before I put them into the new trim pieces.
I found that installing the lock strip into the groove towards the windshield glass first and seating the other side with a screw driver seamed to work the best for me. Again I used a hair dryer to heat the strip and the bottom corners.
I cut the lock strip with a tube cutter at the start and finish to get a straight cut.
After that I was back to where I started! Nothing too it! After the initial cussing fit anyway. Moral to the story, Get the assembly order right.
