Transmission Wiring Harness Diagram

Does anyone have a diagram that outlines the wires from the A4LD in an 88?  I finished the 5 speed swap in my car and everything works great except now when I let the clutch out the sentry lights come on for the low beams and the tail lights.  When I push the clutch in, they go out.  Seems to me that the safety switch on the clutch is back feeding somewhere. 

I cut off the old pigtail and used a 4 pin deutsch connector to tie the reverse light switch in and bypass the neutral safety.  I terminated the other wires.  I feel like I did this correctly because the car starts, runs and drives great but maybe I missed something.  I'm just trying to get the sentry straightened out.

I did some more searching on this topic and came across this thread.

There is a link in that thread that no longer works. Is there an archived forum?

Rod K Do you have any info on this?

So I've learned that if I ground the white/pink wire coming from the neutral safety switch then the problem goes away while the car is running. The idles drops to normal, sentry works correctly. The problem with doing this is that if you ground that then you cannot start the car because it defeats the safety switch.
I pulled the module for the warning lights and it is the same part number and pin out as the 5 speed car I got the transmission from.

I finally found a wiring diagram and I still think the changes I made to the automatic harness should make it exactly like a manual harness.
