need help wireing aftermarket dimmer switch

I got some aftermarket LH and RH controls and I'm having a hard time wiring the dimmer switch on my '81 KZ1000-K LTD. I've mapped out the turn signal and horn but the dimmer is more complicated. Here's the diagram -



Basically, I need to know what the Blue/Orange and Blue/Yellow wires do respectively. The new LH control has 3 wires for the dimmer.

I also got a RH control that has a 3 setting switch that is - lights on, running lights, lights off which has 4 conductors. Here is wiring for the new controls-

Dual sport LEFT side universal switch wiring details:
Gray: Turn signals +
Light blue: Right turn signal
Orange: Left turn signal
Light green & dark green: Horn switch
Blue with white stripe: Headlight +
Dark blue: High beam
White: Low beam

Dual sport RIGHT side universal switch wiring details:
Black: +
Brown with white stripe: park lights
Blue with white stripe: headlight
Brown: running lights (Turns on with both park lights and head light)
Yellow with red stripe: Start button
Orange: Engine switch +
Gray: Engine on
Blue: Engine on

Any help would be very much appreciated.

I'm bumping this one. The most important thing I need to know is what the Blue/Orange and Blue/Yellow wires do. Once I've got that, I think I can get the rest of it (no guarantees). Thanks.

Looking at my 82 GPz1100's wiring diagram, I see that BLUE ORANGE is low beam and BLUE YELLOW is high beam.

Does you bike have the reserve lighting device? It's designed to switch to high beam at a reduced voltage if low beam burn out or if high beam burns out to change to low beam. I'm not sure when Kawasaki included it on the bikes.

how about a picture of the wiring harness/diagram?

yep, it has the reserve lighting module. so the way the dimmer is set up on the factory LH switch is sort of like two switches in one -which is going to complicate things a little as I've only got 3 conductors to work with. do you know what red/black and red/yellow do?

Plummen, here's a link to the full wiring diagram (tried uploading it here but resizing blurs it pretty bad)-

The wiring for the new controls look like this -

Looking at my wiring diagram again I see the RED BLACK wire ties into the high beam circuit after the dimmer switch but before the headlight. RED YELLOW is the low beam circuit coming out of the dimmer switch.

So, I'm guessing the blue/orange and blue/yellow are ground and the red/black and red/yellow are positive. if that's the case, could I by-pass the reserve lighting module and run black/yellow as my common (on the switch) and then to red/black (high) and red/yellow (low) respectively? Thanks for the help so far by the way.

I wish I had a scanner, but I'll list how my bike is wired for the headlight circuit:

BLUE YELLOW is high beam going into the dimmer switch.

BLUE ORANGE is low beam going into the dimmer switch.

RED BLACK is high beam coming out of the dimmer switch going to the headlight.

RED YELLOW is low beam coming out of the dimmer switch going to the headlight.

BLACK YELLOW is the ground circuit color for the Kawasaki's, so I'm not sure how any other color would work.

Your aftermarket switch is a single-pole double-throw switch (SPDT). That is not enough to keep the reserve lighting unit functioning. You'll need a double-pole, double throw switch (DPDT) or you can just disable the reserve unit.

Those wires are not grounds, they are the alternative hot leads in case a bulb goes out. I'll try to post what you need to do in a few minutes.

At the switch, the RED/BLK wire is to the high beam filament. The RED/YEL is to the low beam filament. The BLU/YEL wire is the normal power source from the reserve unit. That wire normally powers the headlight (low or high). The BLU/ORG wire is the alternative power source for the headlights. When the reserve unit detects a bulb failure, it will use the BLU/ORG wire to supply power to the bulb.

The first thing to try is to just use the BLU/YEL wire as the 12v source, then wire the RED/YEL as low beam, and RED/BLK as the high beam.

In case the reserve unit doesn't like being disconnected at the BLU/ORG wire, you can just remove the reserve unit, then put a jumper from the BLU wire to the BLU/YEL wire at the reserve lighting connector.

You may have to disconnect the Light BLU/RED wire if you leave the reserve unit in the bike. It lights up the headlight failure indicator.
