What Color is the Brake Switch Wire to Use to Install a Draw Tite Activator Brake Controller

Question:

I would like to know if you can tell me exactly which wire to use on the brake lite switch to tap into without me stabbing every wire thats there. I know that the red wire on the controller is suppose to go to the cold side of the switch. Ford in 99 did not put any plug in for easy set up, supposedly only started that on Explorer in 2002. My explorer does have a factory tow package. It would save me a lot of time and I hate to just stab wires cause Im sure you know what happens in the long run. Im the original owner and have a flat 4 pin on the tow bar. I will be installing a 7 way blade plug to haul a trailer with electric brakes. One other question is , do I have to run a 12v into the plug for the brakes to work or is that just for aux power for some other function such as a winch or interior lites? Thanks for your help.

Expert Reply:

The wire you will want to use on your 1999 Ford Explorer should be a solid green wire. I would double-check with a circuit tester like the # 3808 to be sure.

The 12 volt power source that runs to the 7-way is for auxiliary circuits like a winch or lights like you mentioned. In order for your brake controller to activate the brakes on your trailer you will not need to have this circuit wired up.
