Small update on this project Still gathering parts for this swap, should have just about everything I need in the next couple of weeks.
This car was really badly infested with rodents, the body plug for the clutch was completely gone so entrance into the car for mice was easy.
The entire interior has now been pulled and the old carpets tossed. Digimat harness and controller are 80% out and the passive restraint system is almost gone too. Replacement is with B4 belt system and wiring, which is all acquired. Replacement black carpet (preferred) is ready to go as soon as the floor coatings are done and the interior dewiring / rewiring is done. It has been suggested that I rewire the complete interior with a B4 harness, which makes some sense since there are some yet to be identified cuts in the existing harness. The cuts could be just related to the radio but maybe not, don't know yet. It would also let me install the OE alarm (and by extension the keyless entry) since the 1990 B3 cars didn't get an alarm.
There are some other benefits too like better power windows but also some unknowns that I need to figure out. It's still an option since the dash is out of the car too for cleaning and hvac work.
I need to get the carpet and seats all stuffed back in it (sans dash) before it goes into the garage this fall. There will be other wiring things to do in the near future so the dash is off for a while still, like engine management, european headlights with leveler motors etc.
PS - further update, the water leaks into the rear quarters have been stopped. The water was coming from the seam between the central roof panel and the outer roof side panels. There's a tiny crevice between the two that's filled with seam sealer and in some places it was cracked badly which I believe is how the water was getting in. That seam is under the black covers on the roof where the rails mount. The only other leaks I have yet to deal with are the windshield, which leaks in several spots, both lower corners and upper in front of driver. That will be resolved with a new 97 B4 windshield.
