Where to solder?

Having mended one little transmitter aerial for 1 vehicle I moved onto the car - trial and error and I think I've sussed where the wire came from! The first thought did not give reverse only forwards but a closer look involving my aged jewellers spy glass revealed a tiny stun of wire. A quick test and that's the spot where it goes. Now I only hope my soldering skills are good enough.

I hope that G will mend my zimmer when I break it in a few years time.
