Ok so i was looking through a parts manual for my truck and i see the the 7 plug trailer wiring harness lokes like its a plug and play thing i havent got under my truck to look in detail but does it just plug and play i have the flat 4 plug now..?.? any thoughts?

 

What do you mean plug and play? What has the 4 pin harness? If you have a trailer with the flat 4 pin, you need an adapter to plug into the round 7 pin receptacle on your pickup.

 

well by plug and play i mean that the picture from the parts catalog shows plugs on it.. i have a flat 4 in my truck now i thinks its hard wired .. i guess im asking is there plugs in the rear wiring for a 7 plug to go in or do i have to hard wire it.

 

Should be a plug right under the bumper if your pickup has the towing package.

 

its got a heavy duty frame mounted receiver

 

i have 2 plugs on flat 4 plug and another too. i also have the frame mounted hitch with a plug and i also have a plug on my rear bumper. i have never towed anything and never really looked at the connectors but i have a few extra wires harnesses in my glove box that came with the truck and was told they were part of the towing package.. never looked at it before though haha. maybe this harnes si have is something you need?? ill try and get pics. i geuss im confused with your question though.

 

mine came with a flat 4 hardwired under the bumper, but also had the 7 pin outlet in the bumper. went to the dealer and got the 7 pin to flat 4 connector for $12 and eliminated the need for the hardwiring. sounds like maybe thats what your truck had done to it also?

 

I think even if you do not have the tow package there is a factory split connection behind the bumper. If you can get a factory "pigtail" you can disconnect the factory split and "plug and play" the 7 plug into it. If you don't have plans to use trailer brakes and aux. power Hoppy makes a 4-7 adapter for the lights. What you may have to do is manually connect wires for aux. power and trailer brakes. My old chevy was that way, but my dodge came prewired with a 7 plug in the bumper and four plug behind the bumper. Hope this makes sense.

I see you are in Iowa, Mills Fleet Farm has alot of the wiring harness stuff on the shelf.
