In a bid to replace the sit-up-and-beg registration plate on my bike I have grafted on the tail section from a 2019 FXDB where the plate sits below the rear light, rather than above it.
I now need to piggy back the original running light to power the number plate light on the new unit.
The old light is combined rear light/brake light and has three wires to it, namely: black - blue - red/yellow and I need to know which is the rear light, as I'm assuming the ground is black.
I have the correct Clymer manual for the bike which under Wiring Diagram helpfully states See CD; I have the CD but no means of playing it
Equally helpfully, the new light has two black wires only !
Can anyone say with certainty Blue or Red/Yellow ?
