Tow bar electrics Gen 4

l got my tow bar second hand and there were either no instructions or l've lost them.

I fitted the tow bar and wiring harness but there's a two pin connector left over on the tow bar harness.

l've looked on Youtube for videos showing how to install the wiring and it only says that the connector is for "specific caravan applications"

As we want to be able to tow our small caravan with the Jimny, can anyone tell me what l need to do with this connector? The wires look to be heavy gauge so l assume it's some sort of power feed.

 

lt's this connector there doesn't seem to be anything to attach it to.

How many pins has the tow bar connector 7 or 13?

The following guide shows the wiring of both.

If you have a 13 pin socket then it wil be for permanent power, but the 7 pin only have lights, indicators, brake and fog. Unless of course you have two sockets on the back, the additional for power?

At a guess it is the power feed for the 'fridge & battery charge.
On my gen 4 there is a wire that goes all the way to the fuse box and has one of those "bodg'em up" piggy back fuse connectors (so the lid now lives in the glovebox, along with anything else that falls off

lt's got a 13 pin socket.

It's also got the wire to the fuse box. l've connected the caravan and the ATC & fridge don't work so it must be a permanent and switched live feed.

Yes, it sounds like it needs a permanent live (through a fuse).

Does anyone have a wiring harness part number to add the permanent and switched 12v supply to the 13 pin wiring harness (9921U-78R00-000)?

I hope that makes sense...

Yes l could do with that part as well, as l never did anything about the lack of a 12v feed to the electrical connector.
