I have been working on my 7.3 swap for some time now, and have come down to working through all my wiring issues. A little of background, its a 97 7.3 on a 93 IDI frame with a 93 F150 cab. The engine wiring is good, and the engine runs. My issue is when I hit the brakes my dome lights and door lights come on. There are also two plugs under the dash for speakers, lights, etc. One of the plugs works but the other has different wire colors and a different plug. I am having trouble sourcing good wiring diagrams for the trucks so I was hoping some of you could help me out. Here are some pictures of the plugs that are the issue (the black one is from the dash and the grey is from the cab):
