Towbar Electrics


Recommended Posts


Fitted a detachable tow bar to my Focus 2.0 TDCI (05) at weekend and started with electrics. All wires are are connected except 12v supply to Interface Relay. Question is..... can anyone recommend where I should take the feed from for this?

Does it need to be a constant 12v supply or does it need to be switched via the cars ignition switch or does it not matter?

I have located a couple of constant 12v supplies on the left side (as you look at the back of the car from outside)of the boot. These wires go into a black multi way plug and socket. Should I tap into one of these using a 'Scotch' connector?

PS out of interest, there are 4 or 5 square sockets on the LHS of boot - what are these for?

Thanks for any help.

Thanks, couldn't find the wire you referred to on the RHS of boot. However, I found that one of the sockets on the LHS had a 12v feed which I used instead. All works fine.
