also macmac do you need to leave ignition on for cig lighter to work
regards ffc
Yes, you do on my kangoo but I took the chip out of one key so it won't start the van. This is the key which I leave in to run pump.
I have had a Halfords plug melt on me before but I only taped the wires up inside. When I got a new one I soldered them properly & it never happened again. They do have a fuse inside & I would advise you to buy some spares while you're there as they are a odd size & not available from just anywhere.
The Halfords plug, to be honest, is not the best quality but does the job if you fix it up properly. The one which came from cleantech is much better quality, the whole box, pump controller, cable/plug has given me no problem in the two years I've had it.
Might be an idea to search out a better plug when you get time.
