Title: Hows your dash wiring?
Post by: Greg H on September 16, 2014, 05:01:15 pm

Has anyone had the pleasure of seeing your under dash wiring harness and felt mildly crook about the way its been chopped and extended to suit rhd?
Im looking at mine now trying to figure out what has actually happened here.
U cant buy complete harnesses ready to go for rhd can you?

And would anyone have a wiring diagram for a 69 boss with tach?
Found a non tach in boss302.com but its a fair bit different.
Cheers

Hey this might be a silly question but while i have the dash out  is there any reason i cant find relays for the lights? Did cars that age not run any or has some muppet ripped them out.
Found one in the enginebay but was dodge wired up to tach wire and back to ignition barrel.
Is it worth trying to put some in?
Cheers

They always had a problem with voltage drop for headlights. With halogen globes now they recommend on the  as mustang  sites to fit relays

I don't know why people make such a mess of a harness, just to go RHD. It's really quite simple to convert one properly and with minimal alterations. There are not many differences between a tach and non tach harness, though they vary right through to the alternator.

After a new soldering iron, coil of solder and heap of shrink wrap ive got it where im happy to put it back in and be confident nothing should catch on fire, still need to run new wires for courtesy lights in doors as they were chopped out and taped up.
Haha yeah dunno sean, unless the bloke was hammered drunk when he rewired it i cant think of any other excuse why it was so messy.

If you need anything, Greg (even pics), I have both tach and non tach harnesses out of cars that I can send info on. Happy to help.
