Re: Trailer Brakes!!! HELP!!!

How do you have 2 greens, 2 yellows and a brown from a 4 pin connector, Pooly?? That is 5, and you didn't mention the white that should be there.<br /><br />Here is standard wiring: <br />Green: Right turn and brake.<br />Yellow: Left turn and brake<br />Brown: Clearance and taillights.<br />White: Ground<br /><br />For a 5 pin, add:<br />Red: backup lights (reverse disconnect for surge brakes)<br /><br />For 6 pin, add:<br />Blue: electric brakes (from controller in truck)<br /><br />Seven pin is mostly different:<br /><br />Brown: right turn and brake<br />Red: left turn and brake<br />Green: tail and clearance lights<br />Yellow: Auxiliary (center pin)<br />White: Ground<br />Blue: electric brakes (from controller in truck)<br />Black: Auxiliary +12V/battery charge<br /><br />Maybe you can select what type you want and get it wired up ffrom that.<br /><br />Good luck.

Re: Trailer Brakes!!! HELP!!!

the two green and yellows are connected in the connector...i guess i just forgot the white...knew what it was..it was strange for me to see also...that was why i asked...<br /><br />so i need a six pin harness...<br /><br />i assume i have electric brakes..there is a drum on each wheel of rear axle..there are no other brake parts that i can see and has just a standard 2" ball hitch..

i tow a 24' ft enclosed car hauler. i have a seven pin connector and a brake box in the cab to controll the brake for on the brakes of the trailer. most of you trailer shops care them, along with autozone for a 65.00 dollars

Re: Trailer Brakes!!! HELP!!!

exactly what do i need to install a seven wire plug to control a 18' tandem axle trailer with brakes on the rear axle?? the trailer will towed with either a 88 Ford Full-size Bronco or a 1999 Ford F-150. Both have just a 4-pin flat plug on them..

Re: Trailer Brakes!!! HELP!!!

You need a 7 wire "kit" to wire truck and trailer. Follow the code above, and the directions that will come with the kit.<br /><br />If you don't have one yet, you will need an electric brake controller. Install it following directions.<br /><br />OR: Take both to a reliable trailer hitch or trailer dealer and pay them to do the above.<br /><br />Good luck.

That is a coverter plug for us guys who tow toys with and without brakes.<br /><br />You need a seven pin on the car and the trailer wired properly for the trailer brakes and all lights to work.

I would like to add that while you can get brake controllers for $50 or less, go ahead and spend the extra to get a better one. For $75, I would highly recommend the one I use, a Tekonsha Envoy. It is a snap to set up and works flawlessly.
