So today i started on replacing my heater core. i have done this on a mustang once before, and it was such a pain. it sure isn't any easier doing it on a supra.. i just came up here to check on my laptop, how to get to the actual heater core out, now that i got the dash out of the way... And who's idea was it to screw all the wires on the dash were you can't get to them??? There are a lot of little things in this cars that don't make too much sends.. well, not to me. Good thing this cars are bad ass, or i would just say screw it.

You don't need to unscrew the harness from the back side of the dash. Follow it along and you'll see the plugs where it disconnects from the chassis harness.

And yes, the job sucks.

the thing is thought, that i couldn't even see where the wires were going to cause they were all hiding behind the dash. all screwed down with plastic.. so i just unscrew them.. i wont next time. I'm not all done yet, i ran out of sun light. i don't have a garage, so i have to do everything in the parking lot of my apartment. it sucks

Chalk it up as a learning experience.

I feel your pain with the apartment thing. I've made an art out of borrowing garages.

As long as you're already in there I'd spend a little time working on some things you can't get to otherwise. When I pulled my dash for the heater core replacement I went ahead and sanded & painted the dash reinforcement bar (it was bad rusty, got rust stains over everything it touched). It looked better, and was much neater to work with and around. I also went to the trouble of redoing all the foam in and on the air box and ductwork. The foam that was there had all deteriorated long ago (it's an '88) and was allowing air around all the different baffles and doors which couldn't seal anymore. Made a noticable difference when I had the fan on.

Oh, a couple of fair warnings. The wiring harness plugs behind the drivers side kick panel were a serious PITA to get loose. Just wouldn't release without a lot of cussing and dire threats. Also, the dead pedal will have to be pulled if you haven't done it yet due to the bolt/screw hiding behind it which holds a panel in place. The head on the bolts on those things tend to rust, so they may give you some problems and try to strip.
