Hey guys. So im getting ready for Sturgis, I got the trailer were taking ready. I got the TBC hooked up to the Ford pigtail. Then I went searching for where to connect it under the dash. I havent found anything. I did find two plugs that werent hooked to anything but they are flat connectors not the bullet style on the pig tail. Can anybody help? We leave in like 2 weeks. The dash lower panel under the steering wheel and the dash "bezel" Is removed. I can see everything except that darn plug. Thanks in advance. 2005 F250 6.0L

 

it depends on whos trailer brake you are using. are you install an oem unit?

 

Its an after market controller. My friend had it in his f150. The pigtail attached to it is the same one that came with my F250. Same part # and everything. It is a six way plug that uses bullet style connectors. The manual that came with my truck tells me where it is and what it looks like but i cannot for the life of me find it. Could it be that the plug is not wired under the dash. Or could it be that something else is hooked up to it? Or maybe the 05s use a plug with flat connectors. like i said i have two of those dangling in there but not the one i need

 

man I gonna go off on a limb here and take a guess at what I think I remember. I wanna saw its taped up on the harness near/behind the e-brake controll. kind if next to the firewall.

 

ok im on my way out to the truck to do some searching. Ill let ya know what i find

 

alright heres what i found. There is a connector with 4 wires. It uses flat style connectors. The colors of the wires are white, blue, red, and green. They are powered as follows:

White-Ground
Blue- ?????
Red-Constant Hot
Green-Power FROM brake pedal

does this sound right? My other question is the package in the glove box came with the pigtail(6 wire) and another connection with 4 wires but the same bullet style connector, and a fuse/relay. Where does this relay go. I just got "hired" by a family member and now im supposed to pull this trailer tomorrow. Hell of a time to figure this out huh?

 

need to look in the owners book. check the fuse /relay pages. look for brake controll. it will be either under the hoos in the bjb or under the steering wheel in the cjb.

 

Follow those wires back. They may lead to the factory brake controller connector. You may be looking at someone else's aftermarket wiring harness. What you're describing sounds just like the Tekonsha harness I have for my P3.

On an 04, the brake controller connector is on the right side of the access compartment under the dash. On the right side is a steel dash support with a triangle hole in it. It's on the other side of that steel dash support, through the triangle hole. It is attached to the support.

That's on an 04, though. I think the plug changed in 05. But I don't know if the location changed.
