I hate electrical

I've had my car out a few times since cleaning up the bulkhead and the car is running flawlessly. My new issue is my reverse light on the dash and my backup lights are now not working. I look at my wiring diagram and my bulkhead connectors and i see wires in places they shouldn't be.....I took a break from it cause I was getting annoyed. I'll get back at it soon when my frustration level subsides. Does anyone have a picture of where the wires from the trans reverse switch end up at the bulkhead? I'm also wondering if the linkage from the column for reverse lockout mechanism is out of adjustment since I had to play with that a little when the connector which holds the rod up to the column was not connected to anything after I put the car in reverse. The sleeve on the column was spinning freely. Its always something.
Well I was able to figure out my backup light issue. The harness that goes from the bulkhead to the reverse switch on the trans has a bad splice. The wires are crunchy from at some point resting on the exhaust. I have backup lights again but I will need to either remake the harness or find a new on that goes from the switch to a connector to the bulkhead.
