Thanks in advance for entertaining my questions. If this question has already been answered please just direct me to it. I have an 2006 F150 XL with 4.2L it has a 4 pin connector and I need a 6 pole round for a new trailer. I have purchased a 4 wire flat to 6 pole round and 4 wire flat Hopkins Adapter. It says it is an easy installation, no cutting, no splicing, plug-in simple. My question(s) is/are. Where do I find the blue wire for electric brakes, and where do I find the (red) aux power wire. The 4 flat is obvious where it goes but for me to not cut or splice the red and blue, I must be missing something. Any help is truly appreciated.

 

Follow the wires back from your 4 pin, up behind the spare tire. You should find everything you need back there.

 

Thanks I will look into it tomorrow morning.

 

I took the spare tire down and followed the original 4 pin back to a wiring harness that has a blue coming in and on the other side it has something like a blue dust plug on the opposite side. When I take the blue dust plug out it appears as though it will take a male connector of some sort maybe. The blue wire on the hopkins adapter has what looks like a male connector that once you place the blue male wire or connector in it you would crimp it. There is also on the truck wiring harness above the spare tire a orange wire coming in on the opposite side of the blue wire with again a blue dust plug on the outgoing side. The red wire on the hopkins adapter is the same as the blue with a female crimp type connector. Any ideas? Am I even looking at the right wiring harness on the truck? thanks again. Hopefully I explained it well enough.

 

That is all for connecting a factory 7 pin connector. No crimping required.

Sorry if I am missing something. I need a 6 pole round connector for my new trailer.

 

I am not aware of a 6 pin convertor that requires no splicing. The reason is there are 2 wiring schematics for the 6 pin plug. On the truck the orange wire is the 12v aux or trailer charge wire, and the blue wire is the trailer brake feed.

I would consider putting a 7 pin plug on the truck. This has been the standard in trailer wiring since 1997. There is no alternative wiring in the 7 pin so you know it is always right. If you get the wrong wiring schematic for the 6 pin it will lock up the trailer brakes.

My suggestion...move in to the 21st century and upgrade the truck and trailer to 7 pin.

 

Thanks for the reply, is the 7 pin for the truck plug and play? How hard is it to convert the trailer?

 

Yes and the trailer plug just requires the purchase of a new 7-way trailer plug as well as installing the 6 original trailer wires and putting them in the correct location in the new trailer plug.

 

OK 7 pin it is, where do I connect the purple (BU) or reverse wire on the adapter?

 

Ford's reverse wire is brown with a green trace. It is in that wire bundle on the harness.

 

Thanks again. Does it matter that the wire going to the reverse light is black with pink?

 

another possibly dumb question...

Do I have to purchase a brake controller, or is there already one in the truck? The truck came with only a 4 pin flat from the factory???

 

You need to get a brake controller. There is a plug for it back there somewhere behind the dash. It will work as long as the harness at the back end of the truck is properly terminated in a 7 pin connector and you put the relays in.

 

What will work?

I will get a brake controller.

And also from what I gather, I need to get and install some relays...
