Also. the guy at the garage told me I needed to change the fuses as I would blow them, he said. Amy of this true?

Without seeming blunt - I would have thought the best way to find out would be to call the people you are renting the trailer from.;)

However most trailer rental places have adaptors in stock (but they are only a few $'s from most autopart places) Autopro/Supercheat/Burson's etc.,

Change the fuses - no I don't think so. The only issue I know about is that D3's don't like trailer lights that are the LED type, but there is a fix for that as well.

Do a search in the tech forum for D3 trailer (sometimes spelt trailor) and I am sure you will come up with the right info.

trailer rental places usually have a socket on the trailer they then lend you the appropriate cable to connect from that to the back of your vehicle..

unless theyve screwed the wiring (it does happen) on their side you shouldnt blow fuses but make sure you know what ones do what in your vehicle before hooking up the trailer JIC.

If your going to a place that also leases trailers that go behind 24v vehicles they may be fitted with a series of "droppers" that cut 24v to 12v, these are pretty primative and have a much larger draw on 12v this is occasionally enough to blow fuses.

Wow I post before I go to bed....get up and check and I have all of the information I will ever need on tow plugs.....

I Love this site :D

Thanks again all.....

Not really almost all horsefloats have clearance lights attached


oooohhh Pretty, pretty, shiny, shiny.

Hello all,
The blowing fuses bit comes in when you fit a replacement alternator with a much greater ampere rating.
Although it is still classified as a 12 volt unit, the system voltage while running can get up to 14.6 volts. This causes a bit of extra current and the old tail lamp 5A fuse gets a bit hot. Put in 8amp fuses to overcome.

Better still, also put in extra relays at rear, to give separate supply and use outputs to drive one of the fitted the rear and towed units.
You can usually only get to interupt the rear wiring to one fitted light set due to the wiring harness location and where they have split it out.
Hope this helps.
