My truck doesn’t and I’ve been planning to do it but haven’t as yet.Mike, it take it your truck not have the round 7-pin connector? Just a flat-4?
Until you get the new flat-5 connected you could, if needed, turn the two connectors 90* to each other and insert the 5th pin (bluw wire) of the trailer connector to the brown wire connector of the truck side and then turn on your lights. You may or may not have to connect the grounds.
Or, and you've probably already figured this out, but just in case - use the little key or pin that's gets used to physically keep the coupler from compressing. Just remember to take it back out before you get back on the road!
Also, depending on your truck, you may be able to get a plug-n-play 5-pin harness that T's into a connector on the back side of your tail light. Last time I did that, I think the harness was something like $25.
The Jeep does so before I left the dealer with the trailer I went back in a bought a 7 to 5 pin connector plug. Flipping the plug on a 4 pin is a simple enough trick too. Seems obvious now that you told me.
There’s also the option of moving the safety pin back one hole to disable the piston. The 4 pin I have hooked now in my truck was spliced in but I will agree and tell anyone else reading this that the plug and play T- fitting is the first best option. Any time you splice into wiring you risk a spot for corrosion to enter and cause big problems. Although being dirt cheap to splice it’s time consuming if you do it right. The T-fitting is ridiculously easy and at $25 is dirt cheap too. If I’d did it again that’s how it’d be done.
