Installing Brake Controller in a 2003 Dodge Ram 1500

Question

Question:

I have a 03 ram 1500 and it came with factory 4way plug. I bought a 7 way and installed that. I then purchased a trailer break control and the separate plug that plugs into the module on the floor by the emergency break and also plugs into the break control. I have power to the control but would like to know how to hook up the blue and black trailer break wires from the 7 way to the control? Since I already have power to the control could I just cut the two wires that I need from the control and wire them back to the 7 way?

You are on the right track. Since your vehicle had a factory 4-way and you installed a 7-way the brake output circuit has been partially ran on your vehicle. It stops at the connector that is located under the driver's side wheel well. In order to finalize the installation you must splice into this wire and continue it back to the plug.

I attached a picture that shows what the wire and connector you are looking for. I also attached a help article that details installing a brake controller in a Ram like yours.

The only difference between 7-Way Utility and 7-Way RV is the color of the wires. The pin outs are the exact same so either would work just fine with the other. If you check out the picture I attached you'll see that the functions are all the…

Although we don't offer an adapter, you could construct one very easily. What does the 5th circuit from the 5 pin round connector on the bike power? I'm assuming that the circuits are ground, right turn, left turn, running lamps and brake…

Since the 5th pin of a 5-way is not normally the brake output circuit that is why the brake circuit is not active when using a 5-way to 7-way. You'd have to wire he fifth pin of the 5-way to the brake output circuit on the vehicle side and the…

The length of wire desired depends on your vehicle connection and your personal preference. You want enough slack for turning, but not so much for dragging as you mentioned. A little extra slack isn't a problem and not enough could lead to stress…

Answer 10

The #30717 is exactly what you're looking for as long as you don't need the 7-way to supply anything other than lights on the trailer. You just plug the 4-ways together, connect the white ground wire to the vehicle's frame using the…

You are correct by checking the fuses first. Even if the 2003 Dodge Ram 2500 has a factory towing package with a 7-way that there may be some fuses missing from under the hood. I would double check the owners manual for all of the fuses and relays…
