AUX switch install

smcgillis10 · January 12, 2015

For most of you you don't want to put holes in your new truck. I have a solution for you. If you haven't seen it already.

On some of these trucks (ie work models) you can get upfitter switches that go where your traction control and cargo light switches go.

Trucks with only "traction control" & "cargo lights" can use this. ( if your truck has bed lights or a park assist it won't work.)

Looks like this the empty switch is just a blank. (Does nothing)

This switches are ground controlling. So you can hook them up to the negative of a relay. Mine are on the way and I'll take/show how it works.

Part number for the switch bank is GM 23145158

They are about $60 most places.

Darn, that would be too convenient if it worked for all switch options

smcgillis10 · January 12, 2015

You could probably get it to work but it would be a pain. You'd have to swap wires and you would lose the "logo" that would normally go with what the switch does.

im gonna have to get this...you would still have to run wires into the cab though right?

Yeah. Originally the wires run to the fuse block on the passenger side of the dash to relays and a wire system there but if your truck wasn't equipped with them the wires won't be there.

So you would have to run some wires. I'll be able to tell you for sure when mine come it and I go to install.

Would have been useful to me if the blank was for Hill Descent Control.

I was able to get a part number for the switches out of a 2015 that has seven toggles. I am going to order those and the "upfitter switches". I was also able to remove the individual switches and chrome seperator bits out of my current switch bank, it took a lot of effort but it is possible haha. So long story short I am going to steal the AUX1 and AUX2 toggles out of the upfitter unit and pop them into the unit from the 2015 in the Lane Departure and Exhaust Brake locations and then wire my light relays off of there. I'll get some pics up as soon as possible but I probobly wont have time until mid July. Apparently the switches are at least 10-12 business days away.

For anyone interested I did some research and there are 30 unique switch banks you can order, here's the list with the detais I know for certain:

23145157

23145158 (TC / Dome Light / Blank / AUX1 / AUX2 / AUX3 / AUX4)

23145161

23145162 (Pedals / TC / Dome Light / Park Assist / HDC)

23145163

23145169

23145170

23145171

23145172

23145183

23145184

23145185

23145186

23145190

23145191

23145193

23145195

23145196

23145197

23145198

23145199

23145200

23145202 (Pedals / TC / Dome Light / Park Assist / LDW / HDC / Exhaust Brake)

23145209

23145212

23145213

23145214

23145215

there are upfitter switches with all the options but it only leaves you 1 extra switch, and if you want it to say AUX instead of the exhaust brake, you would need to get 2 different switch sets.

^^ that would be a good option if you want the right logos for the switch. But luckily I don't have that stuff. (Wish I did tho) I only have an LT

As far as I am aware there is only one "upfitter switch" which has 4AUX toggles. Those other part numbers just cover all the other variations of switch banks that control OEM truck options.

Below is a picture of what it looks like once you combine part #23145202 with #23145158 (upfitter).

I've been working on this for a long time and it's very difficult. Each switch does not have its own wires, rather they push buttons that are mounted on a circuit board inside the thing. If you look through my other thread it explains what I'm trying to do, I just haven't finished the project yet because it's so annoying.

AUX1 used to be "Lane departure warning"

AUX2 used to be "Exhaust brake"

I'm going to try using the signal from those two systems to trigger relays for the lights.

Here's where I'm at so far - two switch sets mixed together:

I don't know yet. Still waiting for hem to come in. It doesn't look like the cargo switch has a light. Didn't even notice that before.
