Trailer wiring plug

The factory trailer plug on my 5th gen is a PITA to get too. Everytime I use it I have to lay on my back in the gravel driveway and that really sucks. Especially at 4am when leaving for a fishing tournament. Is there any of y'all that have moved this in a better spot. Or does anyone have any better ideas
Thanks

Hi stumpy,

I think I'd just build or buy a short "male to female" extension harness, leave it plugged into the truck's socket (if you use it regularly), and mount (strap) the other end where I could get to it easily; that's probably the simplest way.

Regards!

Hi Stumpy,

Had the same complaint, we tow just about every weekend and like [MENTION=83083]rigtec[/MENTION] mentioned, I just made an extension cable. You didn't mention if you required the 4 prong or 7 prong portion of OEM plug, but here's what I used for the 4 wire...........Hopkins #48210
Endurance™ 4 Wire Flat Set (48" Vehicle End, 12" Trailer End)

You will need roughly 12" of wire to run from Toyota's 7/4 plug to mounting point by hitch receiver. Make sure you use plenty of die-electric grease when plugging into OEM plug to prevent corrosion.

Ran that setup for a couple of months, worked out nice, but then decided to add trailer brakes to trailer............so, needless to say I needed to upgrade to seven prong connector. After climbing under truck, I found trailer harness could be unplugged from the back of Toyota's 7/4 trailer plug and Hopkins #40940
Endurance™ Ford / Chevy / GMC (OEM Replacement) would plug right in.

I tested each pin for proper orientation and function, all tested correct. Removed my 4-flat harness, unplugged trailer harness from back of Toyota's 7/4 plug, removed 7/4 plug and mounting bracket, then unplugged harness from vehicle side (much easier to extend wires on work bench instead of on your back under truck). Extended wires roughly 12", added wire loom to protect wires, plugged harness back in, routed harness to mounting point by hitch receiver, installed mounting bracket, mounted Hopkins plug, tested for proper operation, all was good.

Spacing is tight between bumper cover (no cutting was required), spare tire (and yes, it's a Nitto 285), and receiver, but it's doable. There is just enough room to insert/remove hitch pin as well..............

If you don't want to cut and splice wires, Hopkins also offers a replacement harness #11141855 Toyota
