Hey all,

I need to track down my brake light issue on the TSTE and have not seen any manual's up for sale with a full diagram.

If someone could scan and send me via email, or photocopy and send via snail mail...it would be greatly appreciated. I need to see exactly where the stop light wires go from start to finish!

Thanks guys!

Yes all running lights work all the way across. No change in the brake light on the right side even when pedal is pushed with the running lights on. When the running lights are turned on the DIC says "Tail-Light" with the little light lit on the DIC for right rear corner. 8)

Mine was all messed up when I got it shit it had a extention cord and a phone cord for tail lights.
look at you Dic computer behind the glove box make sure all your wires are okay there and not melted.... Run a Jumper form one side to the other and see if that helps... look at the colors and should be able to figure it out I will go and see if I can scan my STE suplimental book then PM you for you email addy to send it...

Well with the schematics you sent showing the DIC box connections, I tracked the wires all the way back. Had good continuity through the wiring all the way back to the DIC box but no power on the pin for going back to the right side brake lights (darkblue/white wire). I pulled the DIC box and looked at the wire on the input side instead of output. Just a touch of corrosion...reconnected the plug and WAH LAH...right rear brake light working!! I would have had no idea where to look for the DIC "computer" if you had not said "behind the glove box".

THANKS TO EVERYONE WHO TRIED TO HELP!!! :turn-l:
