Trailer Woes, Tow Vehicle maybe?

[dusty2221]

My ford did this, a fuse was blown. Check the war wagons manual and inspect any fuse that looks like it is related to towing. My issue was identical to yours. I had a fuse panel under the hood, and dash. Took pulling about 5 before I found it.

I was just about to start tracing and testing wires.

Checked fuses and didn't find none blown. Read owners manual and it says " blue trailer wire not hooked up from factory, see dealership". Called dealership and my service advisor isn't a boat dude I guess cause he has no idea what I was talking about. Had to et out today so this was the fix once back at my unit. I'll take the boat to the Nissan dealership on Tuesday to have a master tech check it out

The blue wire is the reverse light wiring that activates the brake release on the trailer when backing up.

It sounds like you needed to tap into the reverse light on the vehicle. Without the blue wire you only have the use of a 4 pin connector and not a 5 pin that you needs.

I wouldnt waste your money at the Steelership man. Take it to UHaul and have them look it over if you cant do it yourself.

Doing it yourself isnt that hard. On the 7pin on the truck look under it and there should be a small screw. This will allow you to unbolt it and change the wire locations, add wires, or diconnect wires. Then all you need to do it match it up to the trailer harness.

If you need to know what pin on your 7pin you need to have the back up connected to then post up, all 7pins should be wired by default the same so that any trailer can connect.

2 summers ago my 5pin to 7pin fell off on the highway, it drug and ruined the 5pin adaptor, it was of course the reverse wire. So i had to rewire the trailer to a real 7pin connector in the campground. Got er dun.

Here's what I got Mike

The center pin (round shaped connector) on the tow rig's 7 pin connector should be hot when the tow vehicle is in reverse. Otherwise you will be applying the trailer brakes when backing up (unless you are backing down a grade, like a boat ramp and gravity is pulling the trailer rearward).

Do you have a test light to verify that the center pin is not hot when the tow rig is in reverse? It should be hot when the reverse lights are on (should be able to check with the key off and the transmissions in reverse). Don't forget to set your parking brake.

If not hot you will need to tap into the reverse lights. I don't know your vehicle well enough to know if you need a relay or if you can just tap into the hot wire of the reverse lamps.

I'll check that out later today. If that's the issue I guess any uhaul shop can do that pretty cheap huh?
