Auto Lamp/Dimmer removal

OK, electrical gurus! I removed the subharness for auto lamps/dimmer, and now have no headlights. Looking at my EVTM, I expected this, but havent figured out the solution just yet.
I called the only guy I know who has added the autolamp/dimmer subharness to a car that was originally standard headlight and he confirmed my suspicions that there is a jumper plug installed into connector 234 on standard headlight cars. Unfortunately, that was 3wks ago, and he hasnt called me back on which pins to jumper together. Claude, Claude, where fore art thou Claude?

Maybe after looking at the miles of wiring that I have removed from this car, I just cannot see the forest thru the trees in my EVTM cause I cannot seem to find what I'm looking for when I compare the standard headlight schematic on pg.77 to the auto lamp/dim schematics on pgs.81 and 84. Connector 234 is pictured on pg.97 in figure 3. It is grey and has 12pins.



Best I have determined on my own is that I need to jumper the two R/BK wires together, and the yellow wire to the LG/BK. Any one care to take a look and confirm/deny?

If anyone has a standard headlight car and is willing to go pull that jumper out and let me know what its got going on, I would greatly appreciate it. I hit the junkyards here, and the thundercats I found both had auto lamp/dim.

This is on an 87 tbird BTW.

Hey Gumby, I have an 87 TC harness sitting in the garage and can take pics of it if you need.  Where should I be looking at?

Did the car the harness came from have auto lamps?

Connector 234 is near the large grommet where the harness passes thru the firewall, on the dash side of the grommet.

*edit, I'll get another pic up from my spare harness.

Ok, this is another harness I have here, also from an auto lamp car. This is connector 234:


This is with the auto lamp/dim circuit plugged in:


From what I understand, a car w/o auto lamps/dim should have a jumper in that plug.

Good info to stockpile in case someone ever wants to delete their auto lamp as well...

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.
