Wow, Lot going on here. I'm going to try and answer these one at a time.
Lee01,
Not exactly there yet......
Maybe this will simplify it.
87's tied together and connected to new 12v source.
30's out to motors(2 up and 2 down).
85's tied together and run to ground.
86's, each one to a different control wire coming from the switch. Dr up, Dr Down, Pass up, Pass Down.
87A not used.
1. Change all of the red lines going to the 85's to black and attach a ground symbol to those wires.
2. Erase all the black lines going to the 87A's. 87A is not used in this case.
3. You already have the red line at the top left coming from the fuse box to the first 87. Just attach that red line to all the other 87's.
78taw72's suggestion to match the wires in the schematic to the actual wires is a good one. Here are the wire colors according to the chassis manual. I have an actual switch wire harness here so this is correct.
driver's side up - dark blue
driver's side down - brown
pass side up - dark blue w/white stripe (Good luck drawing that
)
Pass side down - Tan (light brown)
Thank you for hanging in there. This is going to be a very nice and valuable schematic when you're done with it.
