When I had my panda I wired the tow bar electrics in to the lights at the rear and had no problems ,now I've recently purchased a 500s diesel with more power than my old diesel although now I will only be able to tow 800kilos instead of the pandas 900kilos . Now I was going to local towbar firm for supply and fit because of all this talk of canbus but it turns out they only use a relay anyway which is some thing I can cope with. Any one on the forum fitted one ?

I had one on one of my recent cars. 1.2 petrol. I took the actual tow bar off but couldn’t get the bolts undone on the bit underneath so I just turned the mounting round so it couldn’t be seen. Shame coz I would have given it to you for free if I had managed to get it off. It seems wires were ran all the way to the front for power for some reason. I saw them under the trim when I replaced the seatbelts.

I've got the tow bar on anyone know what colour does what at the light clusters to save me time. Thanks

It should be identical to the Panda, no?
Assuming your old Panda was 2003+

Canbus vehicles require a little fag packet sized box to work the towbar electrics. The box has an earth and a 12v fused feed. The lights of the car feed into the box and the tow bar wiring feeds out. It acts like a relay and takes the power for the tow bar lights from the 12v feed. Dead easy to sort and you can run a 12v feed fron the fuse box in the car under the carpet to the rear. Crack on!

All done ?
