Joe that is just another type of connector that the industry used. The color code for trailer wiring is standard for all hook-ups. Your hook-up uses 6 wires and the case is the ground connection, whereas the white is the ground.I have a wiring diagram if need be,I will get it for you. Gomer | ||

O/K so this is a redundant plug the trlr has 2 of them and it is not specific to trlr brakes. If I understand correctly this is good it simplifies everything. I have an electric trlr brake controler but am unfarmilure how it connects to air brakes or if it even can. Do I need another that is specific or will it work? Anybody want to enlighten me here. | ||

Joe; You might have a control box by the dash with a red light on it and a slide switch to adjust the timing between you touching the brakes and the actual electric brakes kicking in trailer brakes . If you have that little box about 3" X 5" sometimes just hanging down by some wires it means your trailer brakes are electric. They should be hooked up through that 7 pin connector already.

Joe the controller is electrically operated. When your brake lights come on the unit is wired to that and operates the brakes on the trailer. You will have 3 wires on the controller some have four. One is 12v + one to the trailer,one to the brake light switch[brake light side] It may have a 24v set-up also so check all. Color code is [I think from memory] red is +,blue is trailer brakes,black is from brake switch,maybe 4th is ground if wired that way. gomer | ||

Dave I currently have no controler installed I usually pull 4-down and I have a brake buddy for that. I am trying to set up to do it for a kind of medium to large trlr we ar using this time out. (with as little pain as possible LOL) I appoligize for all the stupid electric brake questions but even thou I'm north of 50 I have never had to mess with them. Gomer in my hands I have A Draw-Tite Activator II brake controler it has been in the garage for years. Your wiring comments were dead on ours is 4 wire and although the brake lite switch is 24 volt on the bus I can run that lead thru a reostat and make that signal 12 volt that way. I am still unsure of what position on the trlr light plug it needs to be. Are all trlrs standerized or do I need to follow that wire from the wheels to see where it terminates at the plug to be sure? Someone mentioned it gets hooked to the post the brake light signal wire is on ? That can't be correct. I am also not real sure of the manufacturer of the trlr or I would be bothering them in the morning for sure. The other light plug on the trlr is normal round 7 pin. Least that is what I been calling it. 6 spades surronding 1 large round in the middle. What terminal does the trlr lead coming off the controler hook to? | ||

O/K I found this. It suggests I use power off the battery on the trlr instead of the bus. I can do that. http://www.bsaohio.com/instructs/5500in.pdf But it still does not give me a terninal at the trlr plug to hook into? | ||

I will get my wiring diagram tom and give you the connections. The big center plug is for a constant 12 volts to the trailer for internal lights or as needed inside. The plugs both have written on the sides where the wire connects. white,blue,green,yellow,red,black and brown. gomer | ||

Thanks Gomer this is what I wanted. Looks like I need to verify the blue wire is at 7 oclock coming out of the trlr and I need at least a 10g wire hooked up there coming from the controler. | ||

Personally-I hate individual electric trailer brakes. They are almost impossible to keep adjusted and balanced. The hot setup is using electric over hydraulic disc brakes. You have a single electric actuator on the master cylinder mounted on the nose of the trailer, then the hydraulic lines leading to all the brakes. Brakes are then always balanced, no electrical connections at the brakes to get wet and go wrong. Especially good for boat trailers. Good Luck, TomC | ||

Tom, I just rebuilt a flat bed trailer with hydraulic brakes on it and they are acuated by the hitch pressure,U- Haul uses them and a lot of boat trailers too. Sometimes we have to use what we have LOL gomer | ||

Gomer- commonly called surge brakes. Still superior over individual electric brakes. Only negative to surge brakes, they can overheat on a long down hill. Using disc brakes would be best with surge brakes. Good Luck, TomC | ||

Tom they have the new kits for those surge brakes to replace them with rotor style brakes. The rotor style I think is required for all new trailers. Kits are pricy but worth the cost if pulling in the mountains. Gomer |
