hello im in the process of wiring in the aftermarket controls on my K, I have the wiring diagram and have done some searching and Im pretty sure I got the right side control correct.

my left side control not so much and hence im here asking from a bit of info from the gurus.

I know I have to re wire the turn signals and install a aftermarket relay for them im ok on that

my problem is how to wire the setup I want correct on the left control I want  headlight on/off , Headlight High beam , turn signal

im almost there but want to double check before I blow up the garage .

sorry for my crappy diagram

Thanks for the reply, i seen it and pull some info from it but the wire color are a bit hard to understand

Sorry i just saw that my dislexia strikes again for the start is black/green and black/yellow

Left:

Pin #	Color	Desc.
1	White	High beam, indicator in cluster
2		Open
3	Blue/Brown	Left turn signal - ground to flasher relay Pin 8
4	Yellow	Low beam
5		Open
6	Brown	Ground in
7	White/Yellow	Headlight power in from right combo switch
8	Green/Blue	Load shed relay, F7, headlight power in to right combo switch
9	Brown/Yellow	Horn relay - ground

Right:

Pin #	Color	Desc.
1a	Brown/White	Turn signal cancel - ground to flasher relay
1	Black/Yellow	Power to starter from start button from Pin 6
2	Green/Yellow	Power to lots of things (to Pin 9 via kill switch)
3	Gray/Blue	Shorted to Pin 4 with gray wire (parking lights)
4	White/Yellow	Headlight power to left combo switch
5	Blue/Yellow	Right turn signal (grounds)
6	Black/Green	Power to start button from clutch switch and gear indicator
7	Green/Blue	Shorted to Pin 4 with gray wire (power in for parking/head lights)
