HELP! --Identify severed wires on RH Gen3 Prii.

Try going to a wrecking yard to get that part of the harness. Otherwise, try to see if the dealer can order you the pigtails going to the marker, head and running lights.

 

The Electrical Wiring Diagram (more info) contains this information, along with the part numbers for connector housings and repair wires (pigtails) with pre-crimped terminals.

 

There probably aren't many people with a Gen 3 that have photos of that area just laying around or that want to disassemble their car to take them. On the other hand, I've purchased a repair manual for every car I've ever owned and they've always had wiring diagrams, with color codes. I've never owned a Gen 3, so I don't have a manual. Perhaps that would be your best option.

 

The Electrical Wiring Diagram is definitely where you find all of that information, as Elektroingenieur posted. Toyota does sell repair terminals, already crimped to short lengths of wire, and the part numbers are in the EWD. But they are not as cheap as you'd expect a little terminal crimped on a short piece of wire to be, and the bill if you have to buy a dozen of them gets kind of annoying. At that point, trying to find a good-condition harness in a salvage vehicle to hack off the damaged part of the harness from can become attractive, as Georgina suggests.

 

The pull-a-part in my area shows they have a 2011 in stock. I may get out there Saturday. If so, want me to see what I can chop out of it?
