I had the wiring supplied and fitted a few weeks ago for $125.00 and it took about 15 minutes. Another towbar fitter did quote around $250 for the same job.
Already had a towbar fitted to the wagon when I purchased it last year, but their was no wiring.
Was told the previous owner may have only used it for transporting bicycles etc. and did not need the wiring done.
I can supply the details of the installer if anybody in SA is looking for a bar or wiring to be done.
The Holden wiring kit alone costs that much money. There is a place near me that does towbars, when I was looking around for one I asked about the Holden wiring kit. They said they don't use it and just wire it in. They had their own kit which comprised the socket and a length of cable and some of those joiners to connect the wiring for $15. They said they have never had a problem wiring VE's this way. I did buy the $15 kit and intended to install it, but before I did I decided I'd prefer genuine Holden kit so bought one of those kits and fitted it myself. I am sure your $125 job would not include a Holden kit, if the $250 quote included the genuine Holden kit you are getting what you pay for. My reasoning for paying the extra is I like genuine parts, and car manufacturers like to build cars as cheap as they can. When you look at the wire gauges they are very thin looking and I am concerned that running extra lights on a trailer will be drawing more current through the standard wiring than normal. Might not be a major problem for say indicators or brake lights that aren't normally on for long periods, but the side lights/ tail lights maybe on for some time. In my case I have a 6 metre caravan which has 13 lights in all that come on when your parking or headlights are switched on (the van has 4 white lights on the front, three marker lights on each side, and the normal 2 tail lights and the number plate light, even if you say these lights are just 5 or 6 watts each, that's at least 65 watts for 13 of them which is about 5.5 amps, not huge but what is the current rating of the tail light wiring in the car? Of course another approach with the van if I didn't use the Holden kit would have been to change all the lights to LED's current would then only be about 1 amp for all 13 lights.
Edit - my car is a sedan, but I presume there is a similar or the same Holden wiring kit used in the wagon.
