95 T Bird How Do I...? (electrical)

Got myself a wireless entry/remote starter package. I've gotten through most of the installation (after cutting myself twice, oops). I know for the parking lights I need to get an additional relay, the system sends 12- and I need 12+ but I got that figured out. What I have left though is this:

Door Locks
Tachometer
Auxilary (trunk latch)

The door locks I'm dreading. I've recently found out how to get at the master switch but the booklet recommends IDing the wire colors and working from the driver side kick panel. Well how do I get to the wires there without studying yoga?

The tachometer... yeah anything anyone can tell me will help. I'm looking for an analog signal wire apparently that's at about .5v when the engine idles.

And auxilary, well if they ever mentioned it in the manual it would help... Probably gotta call support about that.

But mainly what's the best way to get at the wires hidden by the kick panel?

take your driver seat out. all the other stuff confused me, but I know that I have a hard time gettin in there to mess with the fuse box and stuff, especially if I was doing something complicated like that. just make sure you d/c the electric seat controls b4 you pull it out.

And battery.

yea that too, but if you dont.. watch out for that light under there... those mothas get HOT!
