Hopkins Trailer Brake Controller Wiring

[wrecker03]

O.K. first, when it comes to anything electrical I don't know anything...zip, zilch, zero, nada. That being said this may seem to be an elementary question but refer to first statement.

 

I have a 2005 2500 H.D. I am installing a Hopkins (Hoppy) brake controller. My dilema is that the harness that came with the truck has 5 wires, the controller has 4 and other than the ground I don't know which wires go to which so I'm hoping that someone can help me out.

 

The truck harness wiring tag says

DK BLU Trailer Brake Controller Switched Output

RED Fused Trailer Brake Controller Battery Feed

BLK Brake Controller Ground

LT BLU Vehicle Stop Lamp Switch to Brake Controller Input

BRN Brake Controller Illumination

 

The Controller says

White Ground

Blue Trailer electric brakes

Black Positive terminal on battery

Red Cold side of stop lam switch

 

I just don't know which wires go to which wires

 

 

HELP.

I hooked up my own brake controller. It's a Tekonsha, but if I remember correctly you only need four of the wires. Mine is hooked up like this....

 

Controller: 4 wires

Blue------------>goes to Dark Blue on harness

White----------->goes to Black on harness

Red------------->goes to Light Blue

Black----------->goes to Red on harness

 

Harness: 5 wires

Brown-is for illumination, Not used in my case

Black

Light Blue

Red

Dark Blue

 

This is how mine is hooked up anyway. I repoed it from a Avalanche that we traded in. I cut the wires so I could see how it was origionaly attached in the Avalanche knowing I could reuse it in the new rig.

 

You do know where the harness plugs in under the dash correct? Little black box with nut on the left. There's only one place it'll fit, and the cover will show the location.

 

Don't forget to place the 40amp fuse in the FUSE CONTROL center under the hood. Hope this helps. Good Luck!

 

UPDATE: Just went back & looked at your post. Your hook up should be exactly the same, seeing you don't have the ILLUMINATION either.

Thank you for the info.

 

Someone told me I might need a 20amp fuse, your saying 40? I think it read on the tag on the harness that you only needed the fuse if you have the second battery backup, I don't have the second battery. Is it pretty clear where the fuse will go in the fuse panel under the hood?

The fuse goes in stud#1 or stud# 2. It is one of those jumbo sized maxi fuses... It may appear that there is something already in there and possibly some paper glued over it, but it is just a dummy fuse.

20 or 40, I can't remember. The fuse that should've come with the harness! And just like the above post says, it goes either in the #1 or #2 slot. There should be a dummy fuse there.

Thanks guys. I knew I came to the right place for good info.

 

I went back and re-read the tag that was attached to the truck harness and it said to add the fuse if your vehicle DOES NOT have the aux. battery. Also it is a 40A fuse, it was taped to the harness from the factory and it went in the #1 post.

 

Good thing they make the connector able to only go into 1 opening in the box under the I/P. There were 4 openings so I plugged it into the one it fit into.

 

So far it seems to be working correctly. When I hit the brakes I see "E1" on the screen and the operation guide said that is what I should see when there is no trailer attached. I pick up my new trailer tomorrow so I'll know for sure then.

I'm picking up a 8 X 16 cargo trailer, tandem axel. I'm going to use it for hauling the quads and I'm thinking of adding some comforts to it so we can use it as a camper also. It would be better than sleeping in a tent. I'm not going to get too carried away. Besides, when I loose my job working here in the automotive ind. I can use it to start up a lawn maintainance buisness.

I just got a 94 Sierra 6.5L with a brake controller and another 6-port connector that has a red LED in the middle. Looks like a mini OBD plug. What is it?

Thanks for your help!
