I'm fitting a tow bar with dual electrics onto my UK '89 525i saloon. I've got the bar on (loved drilling them holes!) and am about to cut the bumper in a sec, then it's on to the electrics.
I've been given a guide on which colours to use for the main lights etc, but have a couple of questions:
1) How do I get the wires into the car, from the towbar? Is there a nice entry point, or do I have to drill, if so, where do I drill to?
2) Where do I wire the 12v wires for the battery & fridge on the Grey plug to? Am I going to have to take a new wire from the fuse box to the boot, or what?

Any help appreciated asap as I'm doing it now! (I know, organised as ever!)


Thanks

Ben
