Wiring and mounting reverse lights to my 2020 7x18 LAMAR Car hauler. Need wiring 7 pin plug help.

Hello, I have a 2013 Tacoma Baja T/X Series dcsb 4wd that use to tow my 2020 7x18 LAMAR car hauler with. I want to add led reverse lights to the back and rear sides of my trailer. Question is which pin on the factory 7 pin connector do I hook and splice my trailer plug to connect to? Which pin on the truck side is for the reverse light so I can match it to the trailer plug pin?

 

Buddy on here showed me it's the center pin in the harness.
Just looked at the pigtail on my trailer which was advertised as 7 pin, it's actually a 7 pin pigtail but it doesn't have the center pin for the back up lights. My truck is 7 pin. I guess I'll have to get some wireless remote lights to put the on my trailer, I'm not replacing the complete pigtail and wiring harness.

 

It kinda cobbish, but you could power them off your aux (red wire) you just would have to get out and flip a switch on the trailer to turn them on.

 

Yea, I thought about that but I think I'll just get some wireless remote lights cheap and install them. Can use them for work lights and flash tailgaters with them this way as well instead of only having use of them in reverse.
