Tailgate Lock wiring...

[Gunn]

I am attempting to make a minor mod that will change my life.... 

 

I recently got my first pickup and added a toolbox (Weatherguard saddle box).

Love the setup, but one complaint is no power locks on the toolbox.

 

Looking at the Weatherguard lock it is an extremely simple design.

I have engineered a way to add a solenoid and make it work but just need to tap into the lock / unlock wire.

 

Once i get everything working i will try and post a how-to so others can do it. 

 

My Question:

Which wire in the harness going to the tailgate controls the lock/unlock. Appears to be about 6 or 8 wires in the harness. I assume most are for the camera and only two are for the lock.

 

Any ideas how to ID which wires are the lock. If i had 8 hands i would fire the lock/unlock while i measure each wire in the harness but that would take a while -especially if there are 8 and i have to find the two reversing polarity on lock/unlock.

 

Thanks in advance,

I forget which two it is.

But easy enough, remove interior tailgate panel, only two go to the solenoid.

It is a low voltage circuit (5ish) so make sure sol. will operate that low.

Plus if you tap the wires there they are more protected from the elements

Thats how I did the remote lock for my Leer topper

Thanks!

I thought about popping the panel off, but dang.... I just bought this thing - 2500 denali HD... 60 miles on it..

I have been driving my 04 yukon for 11 years... 

 

So if i am brave enough to pop the panel open do i just start prying on the exterior of the handle? Looks to be pretty secure- thinking I may have to get to it from the inside of the tailgate but i dont know where to start.

 

I guess i will start googling how to remove that handle - You are right once i get to the lock i should be golden - may need to add a relay... rrr

 

*It just stinks cause there is a disconnect plug right under the truck i can easily tap into the wires there....

 

THanks again,

no leave the handle alone

drop the tailgate, access panel is on the inside

You da Man!!!

That was so easy. Popped the plate off and it was right there. 

Soo close. It fires my actuator but I must need a nicer one. Bought the cheapest one on Amazon and it returns to center after firing. So close, but you just solved my biggest hurdle.

 

Thanks again for helping!

Do you happen to know what colors the wires were? I no longer have tailgate
