Thread: Trailer Auxiliary Socket 1999 HSE

Perfect spot for battery and water tank if you don't like your subwoofers! Will easily fit them.

Unsure what pin the feed for the trailer comes from, I honestly thought the trailer loom ran down the right hand side of the vehicle...

Hi Keith

Well the bass does definitely come from the back the way the subwoofer is positioned. Unless you are a "doofhead"

Maybe i read the RAVE manual wrong, and it is on the right hand side. I shall see no doubt once i start pulling trim off !

Thanks
Steve

What you're looking for I suggest is Connector #1375 /1376. The RAVE Electrical Troubleshooting Manual has a photo and pinouts for this connector. It is located behind the hatch in the rear RHS of the bootspace behind the tail light. Open the hatch and feel around for a spare white connector.

This connector does not provide for all the items mentioned in the RAVE. Some of them are associated with a connector in the LHS of the vehicle. The trailer socket kits sold in the USA have ISO connectors attached and you take feeds from both sides of the vehicle to the centre underneath and connect to the external trailer socket....that's for the USA kit ..

Suggestion: locate C1375 in the RAVE ETC and draw out the connections on a piece ofpaper noting wire colours. In the very bottom of the RHS corner below the tail light inside, there's a largish rubber grommet. You need to make a hole in it to feed the wires through, which connect C1375 with the trailer socket mounted on the bumperbar

I cut the ISO socket from the wires, pared the wires and crimped female spade connectors and pushed them into a 7 pin Hella socket. From memory C1375 provided power for tail lights, stop lights, and turn indicators. The 10 AMP feed, brake and reversing lights etc are tapped from the socket in the LHS of the vehicle. I have not bothered about these. The voltage drop over the 10A feed line is significant and using it to run a fridge is problematic. It's OK for a camping light or a plug for recharging a laptop etc.

If you're wanting fridge etc, then run a separate +12V line from the engine compartment. Similarly for powering electric trailer brakes.
It's interesting... once I have it all hooked up the computer senses the trailer and a little trailer schematic flashes in the instrument panel when the turn signal is used...

In fact I ended up terminating all the wires into a 12 pin 'triple' decker plug which has several large pins for heavy current: excellent

Hope this helps

Hi Hoges

Great info thanks !

I was looking to use the 10amp feed to charge an auxiliary battery i plan to install in the subwoofer space.

Maybe the voltage drop will preclude this, i will check voltages etc when I get access behind the trim

I tapped into the same supply for an auxiliary outlet on top of the sub woofer. I ended up running the fridge for around 4 weeks with no problems. I would have preferred a dual battery setup such as what you are proposing, but finances and time defeated the idea. The fridge would run fine overnight on the battery, then the following day be recharged from the alternator.
