Did a little more work last night on the harness. Ran into the first major differences in wiring between the 03 and the 99. I focused on the Backup light wiring and the starter relay wiring.
The backup light wiring was somewhat interesting. The connector for the back up light wiring (under the brake booster) is also shared with the fuel pump power. The BU/Fuel12v+connector is tied to the the underhood fuse box by the grey fuel pump wire as well as to the c100(d3) with the lt green backup light wire. I believe the backup lights run into the cabin to shut off the auto dimming rearview mirror when backing up.
The difference with the 03 is that the backup circuit also runs to the underhood fuse box to power a backup alarm branch and then continues on to the BCM of the 03 when it outputs from the BCM it changes to light green to power the backup lights. So this changes the color of the wiring a bit.
The backup lights circuit runs from the IP fuse block Fuse 16 to the PNP switch on the tranny. This is a pink wire located at C7 of the C100 connector. This pink wire has to be connected to the PNP connector pin F which is the backup 12v+ voltage . What makes this all fun is that that power wire is light green on the 03 harness. And in my case extra fun because the connectors were also cut off the PNP switch.
So pink from C7 on C100 to the light green back up power wire Pin F on the PNP. The lt green PNP wire runs to the under hood fuse box in the 03. When I depinned or cut out the 03 fuse box wiring I labeled all of the wires with the fuses that they were running to. So this made it easy to figure out that it was the backup wire.
The return from the PNP switch is a Gray wire. It runs to the fuse box as well to feed that branch backup circuit. So I had it labeled Trailer because the fuse on the 03 is trailer/BU. I extended the gray wire and ran it to the light green on the backup connector.
This should be it for the backup wiring. I will type up the starter relay wiring when I get my notes in front of me. The big differences between the 03 is the passlock or whatever that is not in the 99 and getting the right wires connected to the PNP switch.
I will make some diagrams when I have some time.
