The connecter is for a 12v socket if you want it fitted between the seats; there is one also under the dash.
The repeater is an earth issue check the brake line fitting as the light earths through this.
Things are progressing well. We fired up the engine in the car on Sunday which was great!
A couple of questions:
1. There is a triple connector hanging down on the RH side of the diff (see picture). What is it for?
2. All the lights seem to work apart from one of the cycle wing repeaters, although the two LED’s in the unit do flash VERY dimly. Any suggestions as to where to start to trace this fault…
Thanks as always
