7 RV connector for my fj60

MANUCHAO · Oct 2, 2008

Has anybody done this.

Im trying to install a 7 way wiring female plug on my 60.

Where is the best less intrusive way to get the connections from...
I already drill a 2" hole on my 4+ bumper so there is no turning back now....

anybody has diagrams, pics for these? :idea:

Im planning on running trailer brakes down the road...
I have found some diagrams on line but wonder if these are universal and / or apply to the wiring on a FJ60...

Any info is well appreciated......

Manu !! :beer:

The pins on the actual connector should be marked, in tiny letters, near the screws where the wires are to be connected. LT-left turn, s-stop, etc. You'll have two poles left after you connect all the marked wires, one ground and one power for the trailer brakes. You can use wichever for those two, one will be the center pole, normally it's hot. Doesn't matter as long as the trailer and truck match.

One thing that you will run into is most U.S. built trailers are wired like U.S. built vehicles. They have combined stop and turn signal light elements. That presents a problem to a vehicle with separate turn and stop elements like a 60 has.

There are off the shelf converters made to deal with this. The last one I bought ran about $20
I've never had one that worked for very long. Might be just me, might be a low quality product.

I've devised a circuit to work around this and to take the whole trailer light load off of the tow rig's lighting fuse(s). I've had problems in the past with blowing that fuse. I am almost ready to start building these as a sideline. PM for details.

There's some good information at ETrailer.com

Including this diagram.

The center pin is not normally used for the trailer brakes, but is "Auxiliary". It's most often used for reverse lights, though the possibilities are endless. You will need to run wires from the front for 12V & Electric Brakes. Make sure you use at least 12 gauge wire and install an inline fuse near the power source (battery, fuse block, etc.).
You can find quality converters, though I guess everything fails at one time or another.

P.S. You know the converter is to convert from Japanese electricity to US electricity, right?

7 pin plug

Hi Manucho,

Just did exactly what you are asking on the son's BJ60.

Used a Hoppy convertor, To go from the separate stop/ turn to combined stop/ turn.
The convertor I used has a hot wire going to it from a fused circuit. This supplies the power to the convertor and the switches for the signals/ stop/turn only are used to control the convertor on and of for the various circuits. That way the draw for the trailer lights is coming from the fused circuit so you can have as many bulbs on the trailer as you fused circuit will take. The signal light, stop light, and tail light circuits on the 60 are only used as control circuits for the Hoppy controller. This way the draw on the 60 stop/ tail/ signal circuits is only very small as the Hoppy controller is essentially acting as a relay.
The Brake Control circuit is separate as it is controlled by your brake controller. The extra hot circuit is separately switch as well as you can use this for lighting in side the trailer or for a hand held spot light connection or any else that runs on 12 volts.

If you go the Hoppy site I'm sure with a little digging you can come up with a number for the convertor.

Did it 1 1/2 years ago and hasn't missed a beat and has towed a few different small trailers without a problem.

Hope this helps.

Thanks jb

Hi the JB...
Thanks for the info on this.....
Now the converter you used was it a 4 pin or a 7 pin ??

I will only be towing one trailer on this truck... so I went ahead and splice on the driver side rear quarter panel and got juice from there to the trailer.... I dont foresee getting too much of a draw from the trailer as I'll be running all LED's..

Here are some pics of the way I ran the wires....

Hope this helps someone out there...
