ok my 06 ram did not come with a tow package so I had the dealer install a hitch and wiring.....the problem is the did not hook up the blue wire from the dealer installer wiring to the harness under the dash I have looked everywhere but the right spot..I cannot find the blue wire that comes out from the blue plug under the dash into the engine compartment. Any help would be most appreciated

Did you look under the hood for it? When I installed mine I left the blue wire under the hood until I need to use it.

Yea, they left the blue wire that goes to the rear plug but I'm trying to find the factory wire that comes from under the dash to under the hood????

So they placed that wire inside your truck??? If not you need to run that one inside...

No they left the wire from the 7 pin plug under the hood rolled up and not connected to anything....my question is where does the wiring from inside the truck come out outside the truck so I can make the connection

You need to drill a hole through your firewall, then you can do whatever you want with that wire so you can hook it up where you want inside your truck.

Thanks I was really hoping to avoid that

Sorry that is why I have never ran mine inside yet!!

Thanks

You are welcome!! Have fun!

question of the day, does yours have the factory plug on the inside for the brake controller harness to plug into?

If so the wires are ran to the main plug directly under your drivers floor board, up by the inner fender, you will find the wire on the front side of that harness, Test it with cont. tester or ohm meter.

If no plug then put a hole where the clutch would go throught the firewall with about a 1/4" drill bit, its plastic so you wont have to worry about wires shorting out etc! hope this helps!

I was able to push an awl through a grommet in the firewall that would have been used in a manual trans truck I think. No issues.
