Hello guys.
Found this quad for a decent price recently. Runs and drives but the wiring is a mess. Previous owner did some self modifications including a hotwire job for the starter solenoid / relay.
I've got the wiring diagrams but non of my wires that run to the rear are factory colors / mismatched wires.

I need a little help grasping where the all the rear wires go (Tail light, starter relay, grounds) etc.
Pictures / notes any info would be great!

Thanks in advance.
PS: First thread/post here but most likely wont be my last with this project.

 

Assuming everything is working the lives should be pretty easy to work out with a volt meter, just make sure you've got a good ground then put the live to one wire at a time and toggle through your switch gear, when you get a reading you know it's for whatever you've just switched on.
