I need wiring help REVISED Sketch
« on: March 05, 2015, 04:36:14 PM »
I have my new 850 T3 headlight wiring harness installed ( ;-T to Greg) and am trying to match up the switch I have. The attached picture shows the switch and it functions function on the left and the stock bucket wiring on the left. I have looked through Carl's wiring harness drawings and cant find anything that looks exactly like either my switch or Molex. It seems as though I need to spice two of the wires on the left to account for 2 empty spaces on the right. Even if I could figure that out I have no idea how to place the wires in the Molex.

Does this make sense to any of you wiring Guru's?

Radio shack sells male pin strips that fit into the stock female connectors in the harness plugs.

I have pins and connectors just need the orientation in the connector.

I think this might be the drawing you are looking for an 74T USA, there is a 74T for Europe as well
You didn't give a year.
I'm not sure you can go by the colours Carl used it's very hard to make a drawing match reality. Trace the wire back from it's destination to be sure.

Look at the large circle it shows 2 connectors upper 15 pin and lower 12 pin

Don't go by the numbers on Carl's drawing it doesn't match your sketch, figure out where each of the 12 wires go and match the switch to the task.

I think it does match. I had line 7 mixed up. It should be green/black and white (left turn).

This is going to take me a lot of beer and fuses.

I have a schematic I constructed when I replaced my T3? Stock switch with a modern generic version. It identifies functions by wire color and Molex pin. I'd be happy to send you a copy if you think it will help. PM me your email addy if you would like a copy.

Flicker is down at the moment so I can't see the drawing.
Sounds like Carlo has you covered though.
