It's time to replace the wiring harnesses that run through the tailgate hinges. I have broken wires in both, with pictures at the following link:

I've purchased the Volvo OEM wiring harnesses from IPD and am ready to go. But the replacement wiring I have does not replace the broken wires I see in the hinges.

There seems to be some extra black wires running alongside the wiring harnesses. On the driver's side, there is one broken wire and the passenger side has 2 broken wires. Again, both of these are outside the wiring harness and are NOT included in the kits I received from IPD.

Are there other wires that run alongside the wiring harnesses? Where do I get these? Does this look like some type of modification?

I want to be prepared before pulling this apart because I this is a daily driver for my kids and their jobs.

Thanks for any pointers.
