Hi

Imagine my dismay when I rewired my whole caravan and proceeded to test it. The wiring on the back of the car had been cut and I do not understand where I run the wires to.... Funnily enough i suspect the gas installers ripped it out when removing the tank.... Can anyone please explain to me exactly where the toyota plug is I have found one under the car with 5 pins on it but testing it brought up nothing. I have searched all over the internet cannot find it I know how to wire th plugs its where does it terminate on the cars electricals... thanks

Should be taking it back to the gas people to sort out the mess if they did it.

But it should terminate at one side of the car (rear lights), this is where they pick up the feeds from normally... If your unsure it may pay to have a towbar installer or auto electrician have a look at it..

Hi guys this is my first post / reply. The genuine trailer loom connects into the car loom behind the left taillight, near the jack. The genuine loom comes prewired with flat or round plugs and includes relays to maintain voltages. It is plug and play, but expect some skinned knuckles. When we fitted mine I carefully pulled the trim panel back and it made access better.Make sureyou seat the grommet pr perly as the wet stuff will get in. I also ran spare wires at the same time . If you have reversing sensors Narva have a flat plug that isolates the beeper when the flap is open. Cheers

Re: explanation of where trailer harness goes to.

Hi Fellas. Fitted a trailer wiring harness to my 2000 Prado a month back. The dealership who originally sold the Prado made a right balls up of the towbar wiring and I couldnt stand it any longer - what a dogs breakfast. The original vehicle trailer wiring female socket is above the jack storage area behind the left rear tail lamp. I couldnt purchase a standard trailer loom to plug in so used a probe-lamp to identify which wire was which and tapped into the cables using those splice/crimp terminals. I also took the oportunity to fit high level indicators to the tail lamp cluster at the same time (my Prado is NZ new and only had bumper indicators). I got the lamp holders from a wreckers yard which had a Jap-Import Prado. I just had to drill and ream out the blank fitting in between the other two lamp holders in the cluster and used a pocket knife to cut the appropriate locating slots. It is good to have those high lamps when towing a trailer. I hope this is of assistance.
