Factory (ish) 7/4 pin install on a Hybrid Maverick - DIY how-to

at the taillight harness, green-brown pin #3. I made a jumper so I didn't have to disturb the factory wiring.

That seems like the way to go, where did you source those connectors?

Title suggests, I just installed a factory like 7/4 pin adapter. I didn't want to have the look of the aftermarket 7 pin as they just didn't look good to me. I'd say it turned out well!

The install of the plug itself was nothing difficult. Since it's an Amazon part, I hooked up a spare flat 4 connector from the trailer side we had and tried all the wires to get the color coding (at least the one we ordered, it actually lined up with the factory color for the wiring). I then used some heat shrink soldier butt connectors and it was done.

I've yet to pull the 12v or reverse lights, and a brake controller is coming later (I stay under 2k lbs with the hybrid but I'm in the mountains so I want the brakes) but for 12v, I was planning to use the beds addon dc plugs and then the reverse lights are just a matter of finding the right color and splicing into it.

The cutting and welding on the truck was a tiny bit sketchy for me but it turned out just fine for what it needed. I'm happy to answer any questions about it and if anyone knows the reverse light wire color, I'd appreciate it.

This is fantastic info. Thanks! Just to clarify, this is the part list when your truck already has a 4-pin and your upgrading to a 7 pin, correct?

Yes. Keep in mind, this is ONLY to tap into the taillight harness for the reverse-light circuit, as I explain above in post #2.

Gotcha, thanks for clarifying. I actually don't need reverse lights. Did you install your brake controller yet? I need to do that this weekend and am wondering the best place to route the blue brake controller wire?

I've run a wire thru the RH rear grommet to rear bumper as done for the Lumen Bed Light Kit shows.

A couple of people have run wiring for cameras thru the large rear cabin grommets like:
