**kojak01** · 5th December 2009, 14:24

hi. looking for some advise. i have a 2004 vec c sri estate. i have got my hands on a second hand towbar which is now fitted but the wiring kit that came with it is incorrect. can anyone tell me the if they know or have a place that sells cheap vehicle specific looms for this car. in urgent need but dont really want to fork out twice what i paid for the bar on the wiring!! any suggestions much appreciated. ebay coming in at about 60 quid, the cheapest so far.
ohh one other thing i take it the two multi plugs under the boot floor (in the small compartment) are for the loom to plug into?
thanks

vx do sell a tow bar loom kit i think its about 40.00 it plugs in to the control unit in the boot but i had to have the power feeds ect switched on by vx as it is not programmed to work from factory so if u buy the vx loom then u have the tech 2 cost on top i hope this helps

nice mate. thanks for that. i do remember reading on here about the vx kit but couldnt find it. i know a couple of guys in the local vx workshop so ill give them a shout and get them to switch on power to loom once i got fitted.
thanks again

Towsure also sell vehicle specific looms - check your car's model year (10th digit of VIN) as that's more important than registration year.

Or you could just wire up without the kit. Takes a bit more time, but costs practically nothing. Just a couple of relays and a little time.

On any modern car, it's best to use a 6 or 7-way relay - that way any check control systems aren't confused. The relay will need a 20 amp supply which is available using the red cable to the connector socket behind the trim somewhere - a 20A fuse is normally needed to be fitted in the fuseboard.

You may not need tech2 - I got the Vx kit and it just worked.

I was just posting up an alternative method that is ultra low cost and works without upsetting any checks and balances. Up to the user to how they achieve the end result though.
