Another UPFITTER Question

Ok- so I found the 4 upfitter wires and the passthrough wires. Stupid question now. I'm trying to install a light bar. Do I need to use the up fitter wire and the passthrough wires? If so how does the connection process work. I have looked on this site and youtube but only found videos showing how to find the wires.
Thank you

You connect an upfitter wire to a passthru wire, then the light wiring to that.

I am gonna power my light from the battery, and use the upfitter and high beam wire to control the bar on/off via another relay or two.

I just hooked up my valve for my aux tank, and readied another passthru for my light. I used a 4 in piece of wire. Put a crimp connector on each end. Then stripped the passthru and upfitter and crimped one each to an end of the patch. (The wires are short so hard to join together when I am down on my knees working under the dash)

The first link has a lot of general info links to include technical service bulletins.

The second link has a page with info about the upfitter switches.
