Beginning to install the chassis wiring harness. I found the bracket where the harness clip snaps in, and connected the short white wire tonthe jam switch for the dome. There is s long white wire that goes to the pass. Jam switch. Does this wire follow the main harness, across the top of the dash in the clips? The next question is can anyone tell me the proper place for the harness under the sill plates? There seems to be two possibilities, I think it goes in thebinnermost channel.
