brake control 08 Ram

[pink panther]

I bought an 08 Ram 1500 it has the fuse for a brake control unit and a factory plug for wiring harness under the dash, there is a 4-way flat connector out back that I have hooked to a 7 pin connector, I need the brake control to tow my trailer with, there should be a blue brake wire connected to the plug, it is not on the 4-way flat, do you know where this wire is located at?

The truck came with the 4 pin and not the big round one?  Weird, I know all the older stuff like we have is the 4 pin, but I thought anything newer should have the 7.  I know the wire you're talking about, and you have to hook it up outside the 4 pin, but I wouldnt know where to look.

Yeah Dodge service don't mess with them either. I have everything but the wire 

why would you have a factory plug for your harness and not the brake control wire out back???

Are you saying that you have this hook up under the dash but no blue wire? (just red,white and black)

[pink panther]

there is a harness under the dash for the brake control, out back there is only a 4 way flat with green, white, brown, black wires, I have it going to a 7 way jack for my trailer, but there is no blue wire for the brake control that I see anywhere under the back of the truck, if there was I could attach it to the 7 way no problem

Well,I have access to all the wiring diagrams for '08 Dodge Ram's but I am not sure what to look for. Here is what I can get,do you see anything that would help you?

[pink panther]

that's great, how did you get all those?  I have the diagram for the 7-way, I know where the trailer brake controll fuse and plug in harness is, I wouldn't know those without looking at each one

[tactransman]

This pic shows a 7 wire and a 4 wire. Are you sure you don't have both?

[pink panther]

can you do the wiring 7 way at the bottom of the clip you inserted?

[tactransman]

that's great, how did you get all those? 

If I told you ,I'd have to kill you! 

[pink panther]

I didn't see it, but I will look Again tonight, might just had my head up my @$$.  

Thanks for all your help

[tactransman]

Just let me know if you need more and I'll see what I can do.

Thanks for all your help.

So it has the plug for a brake control under the dash but not a 7 way connector in the back?    Both my `97 and `04 plugged right into the factory harness-even same brake control wiring- but they both came with trailer tow packages.

looked last night and only the 4-way, went to the local dodge dealer and looked and they all had the 4-way, didn't see the 7 way on any of them.  I'm stuck now, need to get this done before the Nats.  Maybe a trailer place can figure it out?
