Good evening. new to the newer bobcats i think i have a 95. i bought a plow for my 753 and am trying to get the angle to work. i had to buy a new auxiliary switch that is under my boss system because it was so corroded and wouldn't work. put the new switch in and now the lights light up but the plow still wouldn't angle. so i lifted the cab and the wires for the stick switches were just hanging there. i have a bunch of empty connectors on this harness and cant figure out where they go. my color on my wires differs from all the ones in the manual. This harness looks like it has been replaced at some point because it doesn't look that old. did they change the wiring colors?

The manual says the colors should be

green/red
yellow/white
yellow
dk green/lt green
yellow
lt blue/red
orange
dark green

i have
green/yellow
green
green/red
green
green/red
green/white
yellow
gray/red

Connector in question the bigger connector on the auxiliary control module. My module is located under the cab mounted on the left side. I was going to go by the pin letters on the connector but A and K are blank with rubber plugs but the manual says a should have a pin. So i am very confused. This is a non high flow 753 with a serial 508611787. i gave it to my bobcat dealer and they said they cant do anything with it it doesnt come up.

Sorry for the bad typing i am on my garage computer and some buttons dont work anymore lol.

If that is an aftermarket / homemade harness, all you can do is try and trace each wire individually.

I am trying to but the wiring diagram doesn't have a pin out for that connector. I don't know how to attach a picture to show what I am talking about

I imagine that if you take a picture , put it in your picture file on your computer and from there you can come back to this thread and press on the attach files button which is in the left hand corner of the square you use for writing your concerns. I'm pretty sure that's how you could post a picture on this forum. Good luck.

The colors also don't match the diagram on the switch either but atleast that one shows pins so I can figure that out
