Need "Multifunction Switch Instrument Panel" Diagram

smcgillis10 · October 28, 2016

I've read so many of these and it still seams unclear to me, I have a 2015 Silverado rally edition it and just installed the switch with the 4 aux lights and I have cargo lights and traction control, I don't not have the prongs in my fuze box for this but I all ready have wires run to switches now but want to change them into this switch what's the best way

You have to use these switches to control relays. And they only connect/disconnect the ground of the relay.

Ive got one for you.. I have bought the (7) switch panel with all options and one with AUX 1-4 and swapped out the last 4 options with the 4 AUX switches because I have the first 3 options (pedals, TC, cargo lamps).

My issue: I did not see any fuses in the required location for any of upfitter switches 1-4, and I do not have any of the last 4 options in my truck...BUT I found out I do have BOTH plugs with all required wiring going to the new switch panel. I was planning on adding these terminals as stated in this post and running them to the latching relays, but they seem to be there already. Where do they go, if I do not have those options?

Will I have to tap into existing plug wires for the options I dont have and just run them to the latching relays? I am assuming the wiring just runs to the fuse panel and is connected to the board under fuses.

If you have wires in all pins on the connector then your truck is set up for all options. Like hill decent lane departure. ECT . And those wires go to different locations.

The only trucks what would have the correct wires for the uppfitter switches that go to the relays in the passenger side dash are WORK trucks. Unless you have a work model then you have to rewire the plug.

Easiest option would be to splice into the correct wires for the AUX switches and run them to relays in a location of your choice.

Let me know if that helps.

yeah i have SLT. Would it make sense to cut and run new leads or just strip section and solder in tap? Not sure if I like powering up a line that i dont know where it goes to. Or makes no diff?

I've got problem. I hooked it all up correctly and tapped into the 1st wire which was pin #9 (Parking assist, which i do not have that option) for the switch i wanted to test. It did not power up. So i tested the latching relay and even the NC terminal has no power. Shouldnt that have power all time as long as the board is powered up which it is. Even the test button does nothing. ...Im stumped and just spent 4 hours working on this...

Can you confirm that the COM terminal on the latching relay is grounded. And 'NO' terminal goes to switch on the relay for the light bar.

PLEASE HELP

You hook up the light bar to 87.

Hook the power from the battery with a fuse to 30.

Hook 86 with a fuse straight to the battery.

85 goes to the switch bank.

What's the part number for the switch block that you have. The wiring for the switch block with cargo lights, traction control, and the 4 aux switches is what I posted.

The latching relay...NOT relay for light bar, thats simple

I dont have any latching relays in my system. I did not need them.

why? did you use the switch bank with latching switches?

No just normal relays.

If you got the right switch bank there are 4 latching switches on the circuit board for those spots. And don't require the use of a latching relay.

With the actual uppfitter switch bank. There are 3 momentary contacts and 4 latching switches.

The uppfitter switch bank is. 23145158

Im sorry to bother you, your wrong person to be asking this...

I needed the other switch bank with all the options due to my options that came with the truck. So I have momentary switches, not latching. \

thanks anyway

I gave up on the OEM buttons long ago -- there's space to run five Contura V switches in the overhead panel on my truck, so I'll be doing a five-button "DIY SPOD" setup. Have the switch bank installed; now comes the wiring fun. :-)
