brake controller installation

I'm planning to install a electric brake controller in a 2010 ranger. It came with a four-prong hitch connector, but I need to change that for a seven-prong connector. There is a
connector through the dash, just under the steering column, that I can't find the purpose for in my owner's manual. Can anybody tell me if I have lucked out, and it is for a brake controller, and if so, where do I pull the extra wires for the trailer brakes.

Thanks in advance

I had to run 4 wires when I added a controller in my '08 Sport.
One wire connects to the brake pedal switch, one wire connects to battery (thru a 20 amp circuit breaker), one wire connects to ground and the last wire (brakes to the trailer) runs all the way back to the 7-pin jack at the rear of the truck.
ps. If your trailer has a battery in it, you will also need to run a wire from the truck battery, thru another circuit breaker (30 amp) and run it to the 7-pin jack. This will charge the trailer battery.

Terry, hey, thanks for the help. After much digging, I found out that the connector on the dash is not for a brake controller - I don't know what it's for, but it just ain't for a controller. So, being the brave fellow I am, I took it to a trailer place to get it installed. Glad I did - it took them 3 hours - if it took the pros 3 hours, I'm thinking it would have taken me 6 hours. Even then, there is lots of scope for me to bugger it up...

Nevertheless, thanks for the reply.

That connector under the dash is the diagnostics port. You can pull codes there and re-flash the computer if you have the right equipment.

It should not take a pro 3 hours to install a brake controller. I don't think it took me that long and it was the first time I ever did it. Maybe it took him a long time to figure out where to put it.
