Great upgrade
I upgraded 7pin setup to 13pin setup and this works as treat. It runs my caravan fridge while driving.

Maypole, Good stuff as usual!
Maypole, Good stuff as usual. This unit appears to contain small relays powered separately by a power connection which is supplied from the battery / fuse box. This means that the existing wiring does not have much additional load, just enough to turn on the relay(s) The Buzzer for the indicators is pretty loud as well, can't ignore it.

Works well, but no instructions!
This relay works impressively well - once installed - and that’s why it got 4 stars! On the packaging it clearly states, ‘Instructions Included’, but they simply weren’t. There was mention of a website, but going there led to an indecipherable list of loads of different products, none of the links having the same number as any part number on this item - a tedious search was needed… Even when I found the right link, there was no wiring diagram, just words, nothing like as intuitive as visuals… So, 3 websites later I had instructions and could install. The only nuisance in use is that occasionally the turn-indicator beeper ‘warbles’ unpleasantly and sounds cheap. It’s great value and - subject to these reservations - recommended.

Find about you vehicle wiring colour codes before you start And what side they are send down
Fitted this to a 04 regVW touran fast post good price.The instructions are a bit poor but YouTube is the way to go it took a good 4 hours but was talking care soldered all the connections. Doesn't come with inline fuse or holder. But I had one anyway. It works but doesn't beep but that could be because am using LED lower resistance . But no dash lights saying there's a problem so all is good.Will try some normal lights one day maybe LEDs needs a resistor.

Relay 7 pin
Thanks works good

perfect product
these relays are the only one I will use and have fitted hundreds, never had one break or give a problem, if you are fitting a tow bar then it pays to use the best relay.
