Cheaper at e-Trailer ($102.81) Curt 5th Wheel/Gooseneck Custom Wiring Harness w/ 4-Way and 7-Pole Connector - 7' Long Item # C58FV https://www.etrailer.com/Custom-Fit-Vehicle-Wiring/CURT/C58FV.html

I was looking into this Titan fuel tank. Seems everything stays standard. https://titanfueltanks.com/products/xxl-replacement-tanks?find=2020-chevy---gmc-2500-4839&sid=IZ0goVJdJJ.

I ordered and had installed the same TPMS sensors that we have on the truck into the stems of our trailer tires. They read out under the trailer setting giving you the tire pressure and temp. https://www.ebay.com/itm/373846448395?hash=item570afc190b:g:p1EAAOSwC29hzroz

On the passenger side fuse panel there is a square red fuse block. Move it over to the pin that is exposed and will shut off until truck is started.

I purchased these and they work great when my Jayco North Trailer is selected after being hooked up and plugged in. https://www.ebay.com/p/25034266056?iid=254626319087

These are what are on my 2020 GMC Sierra. I also installed these on my 2021 Jayco trailer and work when that trailer is selected. https://www.ebay.com/p/25034266056?iid=254626319087

They are in blocks of three. There was a Youtube video of someone doing it, but it was removing the wires from the back of the plug and moving them around. Time consuming ans intense.

You will love the built-in sway control on the truck. I had these installed into my Jayco North Point tires. It displays the temp and pressure on the truck's screen when that trailer is selected on the set-up screen. This saves have additional monitoring device mounted in the cab. https://www.ebay.com/p/25034266056?iid=254626319087 Also someone is selling the camera system for this truck.

Here are couple of options. Some are 70"s and some are 60"s. They are white for entering the vehicle, turning signals, and marker lights. They are sequential so they move when you turn on the signals. Tap them into your marker light wiring, your turn signal coming from the back of the headlight, and your inside dome light drivers side floor area (BCM #1 White with the gray wire). Link to do it below. https://www.opt-7.com/sidekick-sequential-running-board-switchback-led-strip-kit/ https://www.amazon.com/LITTON-Running-Sequential-Courtesy-Vehicle/dp/B092CKFN1W/ref=sr_1_4?_encoding=UTF8&c=ts&keywords=Automotive+Running+Board+Light+Assemblies&qid=1641954643&s=automotive&sr=1-4&ts_id=15736501

They are screwed in so take a look at your fender and see if there are cut outs available just not completed by the factory.

That is for the 5th wheel plug. I ordered this item from Curt Item #56072. https://www.curtmfg.com/part/56072 My 110v outlet is on the passenger side same area.
