Does anyone know what gauge wire is used for the tail light wires on a 1971 Plymouth Road Runner?

Thanks to all that provided ideas regarding the "no tail light" issues I had on the 1971 Road Runner that I'm working on from thread - 1971 Plymouth Road Runner - No tail, turn, brake, flasher lights in the rear - most logical things to check?

As noted in the photo, I'm going to have to extend and splice the 6 wires back together that are going to the tail lights as they have been cut somehow. Does anyone know what gauge wires are used for the tail lights on this car? To me, they appear to be a 14 or 16 gauge wire, but I thought someone here may know for sure before I start splicing.

All conductors in the rear body harness are/were 18ga originally.

Recommend downloading the 1971 Plymouth Body Service Manual from MyMopar. For the '71 Satellite/RR the wiring diagrams show 18 gauge wiring for the tail lamps.

Check the condition of the rest of the rear wiring harness and light sockets.
A new harness is $139 just in case the rest of the harness is messed up too.

Thanks for all of the helpful replies. I'll use 18 gauge wire to repair the existing harness and keep in mind the option that a new harness is available for the car.
