Ok so managed to get the bike carrier fitted today, but not without some hassle. The instructions are basic but easy enough to follow. Mostly pictorial.
Something to note, I have never had a vehicle with a towbar before so this was as much about me understanding how they work.
My towbar electrics are the 7 pin type and the carrier has a 13 pin plug. The carrier comes with a 13 to 7 pin adapter when bought from the Roof box company, which is useful....sort of.
The problem is that due to the shape of the carrier and where my 7 pin socket is on the van, using the adapter means there is not enough clearance to actually plug it in Hopefully the pictures show you what I mean.
I considered a few options but in the end I opted to change the 7 pin socket on the van for a 13 pin socket. Bought a Maypole 13 pin euro socket for m Euro Car Parts as they had 1 in stock for collection (£7.99). I followed the attached diagram for the wiring and it was simple enough to connect up, if a little fiddly. Once done all the lights (Inc brake) and indicators worked, but as my wiring loom only has the 7 wires this means pin 8 can't be used which would be for reversing lamps.
Naturally the carrier interferes with the parking sensors, which isn't much of an issue as I can simply turn them off in the van by pressing a button and just use the camera.
Overall the carrier works well, feels sturdy and the barn doors open with a couple of inches clearance once the sliding mechanism has been opened. This mechanism is simple to use. You slide a switch across just above the number plate then push down on the lip just below the number plate.
Any questions let me know.
