4 to 7 pin converter Question

[lhasalady]

Hi All - My truck ( 2007 Nissan Frontier ) already has a 4 pin connector- If I get a 4 to 7 adapter, Is that all I would need?
As far as  wiring the brake controller I'm under the impression the truck is already prewired for the controller with the harness being taped up inside the steering column. Does anyone know if this is right??

Thanks

My Titan has the wiring under the steering column by the e-brake.  Yours would probably be the same.  You will just have to find a place to run the blue wire all the way up to the controller.  Good luck.

You will need to get a 7-pin connector for your truck.  Here is one that accepts the 4-pin you already have, parallels it out to use with a 4-pin trailer connection, and gives you the 7-pin for your trailer with brakes.  I wish I had seen one of these before I wired my van up - I used wire taps to tie into the existing 4-pin harness; alot more mess!

I've never had a TV that was pre-wired for a brake controller, so forgive my ignorance, but when a TV comes pre-wired, does it not include the blue wire going back to the rear to be tied into your 7-pin? It seems to me that pre-wired would include all 4 wires already being installed. That would mean that somewhere in the rear would already be a single wire that you would connect to your 7-pin.

But I could be completely wrong!

My 2000 Dodge Durango was 'pre-wired' (all the wiring to go to the rear 7-pin plug), so my dealership just plugged into those wires under the dash.

My 97 Dodge Ram 1500 (with the heavy duty tow package) was considered a border line model when I checked/got estimates for a brake controller to be installed.  Turned out it was pre-wired, and hitch folks had no problem installing/hooking up the new controller - in and out in 15 minutes with a bill under $100 labor/controller.  (I was soooo tickled)

I do believe that if you've got the tow package with the 7-pin connector, you are 'pre-wired' -- but, I could be wrong.  There might be something in your vehicles owners manual as to what the tow package entails.

That pretty much sums it up!

If your vehicle is prewired with a 4-pin connector, you are not pre-wired for a brake controller.

If you purchased the "HD towing package", or something similar, that includes a 7-pin Bargman connector at the rear of your vehicle, it is pre-wired for a brake controller.  However, sometimes you still need to purchase a short wiring harness that plugs into the quick connect underneath the dashboard and then wire that harness onto your new brake controller.  There may also be some additional relays or fuses to plug into your fuse box to enable the charging, turn signal, and /or running light circuits at the 7-pin Bargman connector.  Check your user manual.

My Dodge Durango, with the factory tow package, came with a convenient sealed Mopar Parts plastic bag with instructions, additional relays, 7 to 4 pin converter plug, and a quick connect wiring harness.  The previous owner never towed, so I found this package unopened in the glove box.
