Well, I got the new seats and harness installed. Drivers seat is a tad tall, so I may build a custom bracket so I can lower it and move it back a bit. The harnesses are attached at the back with a slight downward angle, but are within the harness specifications.

I also installed a remote kill switch since the battery is in the trunk area. I think this is the first time I have ever removed the rear bumper cover (in 15 years). Installation was straightforward, but I still need to run the wires to the front for the ignition disconnect.
