AUX switch install

akkrezz · January 29, 2016

You connect the wiring harness like you would normally do. When your done, program your homelink with the remote it comes with. Just like your programming a garage door opener. To be honest, Id rather have a switch hard wired. While driving I have to press the button a few times before the lightbar turns on.

Thanks for the input man

I found this terminal. It looks the same as the one on the wire part. Anyone got any thoughts on this?

I don't know that it fits but I think I'm going to start here before I drop $40 plus for the gm oem.

EDIT: Found them cheaper here: http://www.digikey.com/product-detail/en/962885-1/A105237CT-ND/3440492

I ordered them. I will post a follow up when I check the fit.

They look very similar, hopefully they will work!

any updates on this?

I did get them in and they look similar. I am still waiting on lights and my new switch before I dig into the dash thought. I will look tonight and see if there is a similar plug visible somewhere else.

Did you ever get this installed?

It's still a no. I have lights but I'm still waiting on the switch and latching relays. The switch will be here next week but the relays are coming from China. I will try and break into the dash when the switch comes in. I need to look for a spot door the latching relays anyway.

I just posted this on colton_m's original post...

I think that I have found a solution for using the OEM Momentary switches to control accessories such as light bars. I have decided to use the 23145202 switch as I have the adjustable pedals. This switch gives me 3 open slots to use. The issue with the switches is that being momentary they will not operate a standard relay. Upon searching I found these latching relay boards that come from China and cost $3 each. I picked up four of them to try, they are 12V boards that use a low input, so when the input is grounded, the relay activates and latches, until the input received another low signal. I assembled 3 of them in a case made a harness for them.image.jpeg

I am modifying the switch to have the correct icon too. image.jpeg

This looks great -- nice work!

Where did you get the stickers?

My wife cut them using her vinyl cutter.

So I started installing everything yesterday and discovered that my truck has the 2nd harness for the exhaust brake port, even though the original switch has a blank port. I think this could be a good thing and maybe I can just add a fuse/relay and utilize existing hardware in the truck. At the very least I now have wires to tap into for that last switch. Anyone have schematics for the exhaust brake?

I also took pictures of the main connector to see if we can find the connector and the correct pins.

Are there any pics of the actual wiring needed to run these to a light bar?

That's interesting that the connector was there even though it was a blank. The wires were there too? I wonder where they leed?

I would think once hooked up you could just ground one wire and test with one of the latching relays. Just use the process of elimination.

I don't really understand why the connector has so many pins. The exhaust brake is not a variable thing is it? (Multiple presses don't mean different things do they?)

On a side note, I am about ready to crack mine open too. I don't have all my lights in yet but I got a box with 6 relay ports so I can just run all my wires and be ready for lights as they come in.

I didn't add any wires to the brake controller connection, it is a complete harness. That's why I am thinking I can just find the stock relay location and utilize the OEM wiring, instead of taping into the wires at the plug. But if not then I will use wire taps and connect my switch trigger to the switch output and then my output to the relay will connect to the indicator ground.

I have everything connected and it all works great! I will have to modify the schematic just to show that the low output from my latching relays is also run to the switch for the indicator lights, so I used two wires for each switch. I have a video that I will try to post later. Everything works just like it would from the factory. Here are a few pics of the wiring while I was installing.

Ok finally got it opened up. I removed one of the wires to look at them side by side.

They look the exact same. Only a slight variation on the clip but they should fit just fine.

Azelkhunter do you actually have adjustable pedals? I don't and was wanting to use them as my fourth switch. Only problem I see is one pin moves pedals up and another moves them down. Should I tap both wires and bring both to the latching relay? Lane departure and park assist aught to be strait forward. I'm right there with you on the exhaust brakes though. Mine had the harness as well which was a pleasant surprise.

Ok so I said that park assist and lane departure should be straight forward. But I looked at the pin list some more and there are 2 pins for these also. Do pins 5 and 6 control the led light on the front of the switch? Did you get yours working?
