Re: Accuracy of TRF Wiring Harness to Bently Diagr
Trickiest part is sometimes finding the wiring diagram that is right for your car... several changes over the years, some just for the US market, not all manuals show all combinations.
Wiper motors in particular had a significant change... as I recall some were with switched the hot lead, others switched with the ground.
Think about the connections to the front turn-signal/side lamps as I believe one filament in that bulb is brighter and that is the one you want wired for the turn signal (if a '55 has turn signals?).. Same thing in the rear with the brighter filament being the brake light.
Some add an inline fuse to protect the lighting circuits (other than headlamps). TR did this for US cars later in the run but it is a prudent addition to earlier cars (goes behind the center panel).
All that said, I found the harness replacement to be a piece of cake... I used the Moss harness but would expect similar results from the TRF version.
