Well, my friend, you are living everyones worst nightmare for pulling wires and aftermarket electronics. Gotta concentrate on the alarm wiring, maybe download (if available) installation information for the alarm system. Good luck trying to find diagrams, I've found them hard to come by.
I have an aftermarket alarm in my 996 that works, but I never use as my car is garaged and we live in a pretty safe area. I find the system annoying as the keyfob would go through batteries about once a month. Also, if we ever made the mistake of trying to unlock the armed car with the factory keyfob, all hell would break loose with an alarm that was hard to disarm (as battery in alarm keyfob was weak). I stopped using the system and thought of removing the electronics but was concerned of running into the exact issue you've run into.
As I've been unable to locate the schematics, I've decided to punt for now. My factory keyfob works great and so it goes!
Your problem may be difficult to find but it will be easy to solve! Hang in there!
I didn't want to, but Wed I removed the steering wheel and binnacle. Figured I had to remove it to enhance my search.
Thu morning while laying in bed, I remembered 2 wires I clipped off that were under the steering wheel. Wondered if the ends that were left happened to be the same colors?
You can't tell from the pic, but there were 2 black wires that went into the yellow connector. The gold connector also had 2 black wires. BINGO!!! Now I wanted to track down the end I cut off. The wire coming out of the yellow connector was green, white out of the gold. I found the section I cut off.
The wire bunch on the right are the green and white wires I cut. They're pinned into the connector that wasn't plugged into anything, so shouldn't have been an issue cutting them. But something interesting half way up the wires.
A jumper wire connecting the green and white wires. This completed the circuit back to the 2 black wires these came from. Except now the circuit is broken since I cut those wires. So I cut the yellow and gold connectors off and spliced the wires together with a jumper wire (didn't want to solder them together and find out that didn't work). Put them together and plugged the instrument panel back in.
Fingers crossed...
Success!
Will solder it up tomorrow and put the binnacle back in. My wire removal project is completed!
Looks like I'll be able to make the TB / WP apt on the 27th - if I can get the 9" of snow off the rear driveway.
