Ive been trying to figure out some things with the car. My interior lights will only come on when the key is turned to accessory or run positions. Its also affecting the keyless entry keypad which Im still trying to verify if it works. If someone could help me with a wiring diagram for that system it would be greatly appreciated.

Well I figured out the problem! First of all I need to figure out how to get under the dash better. I actually got a look at the fuse box and #8 fuse wasnt in there, put a fuse in and low and behold the interior lights came on, but had a slight issue. The radio, clock came on and I could roll the window down without the key rotated. After a little looking at some diagrams I noticed there was a light green/yellow wire that ran from the courtesy lights to the radio.

So I pulled the radio and low and behold one of the PO that wired in the CD player had cut the factory plugs off and wired it up that way. They had the light green/yellow wire wired into the keyed power on the radio. So that would be why the fuse was pulled and when it was put in it would power everything in the radio circuit. Pulled the light green/yellow wire out and taped it off and everything is working as it should. Even the keyless entry works correctly!!!

I am now a very happy TC owner!!

Thanks, I always do my own stuff. Been for years, it just took me a little bit to get good diagrams to compare to what I had and figure out the most likely place that someone could have messed it up.

In addition to this, anyone that has the typical RF interference that has a factory EQ. I have found between the TC and a 5.0 Sport Coupe I used to have that most of it comes thru the EQ's power feed. Remove the power wires out of the harness and install a RF blocker inline. My interference went from hearing it over the radio even with it turned up to almost non-existant.
