Default Does Anyone Know Which Wire

Okay Peeps, I've figured out there's a pinched wire in the steering column that determines whether or not my radio/clock display lights up. When it's dark, I can tilt the wheel just a tad in either direction and it lights up. For a while. Then it goes out and I have to tilt it again. I've got no problem clipping wires and soldering them back together, but I'd like to know if anyone has a schematic that shows which color wire might be the one I need to splice. I don't have a schematic and hate guessing. I'd like to just be able to cut, splice, solder, shrink wrap and be done. Thanks for any help. On a side note, I checked the mileage after a 221 mile trip yesterday and got 25.1 mpg out of the turbo! And I had her cranked up to 95 once for about a 3/4 mile stretch. Had a tractor trailer to get around before it went back to a two lane highway!

I could send you the wiring diagrams I have (01-04 & 07) if you're stuck

There are a few posts on site that say adding an extra ground wire to the column will fix this issue also (if the wire isn't pinched).

#15 protects the wipers, front and rear.

Therefore all of these functions will go off with the radio if the run/acc31 circuit wire is the problem (wipers would be easy to check).

If the power feed circuit to the ignition switch were the issue, at least six other fuses and the associated circuits would be failing
I appreciate the info, man. BUT everything still works except the display on the radio. Moon roof, map light and overhead console are not affected at all. It's very strange. Wipers are not affected either. It's JUST the radio display. I'm going to go out and tinker with it in a few minutes.

Thanks, Sanatanadharma. I found one wire that seemed to "sag" somewhat near the pivot point of the tilt and zip tied it up. So far, so good. It's damn near just too hot and humid to fool with already today if it acts up again. I MAY just leave it alone until it gets to tilting the wheel stops working all together!

My car had the intermittent radio display, along with the key in ignition chime not working. I had checked over all the wires running up the column and everything was just fine, no amount of wiggling, jiggling, pushing or pulling on them made any difference. Playing with the key in the ignition made no difference either.
Adding the extra ground wire, like posted above, cured both issues. I did this several years ago and it's been perfect since.

Thanks for the input, Joel. I found one wire that was close to the pivot point on the wheel and zip tied it up. No problems since. If it comes back, I'll run that additional ground like you did.
