Running wire through the firewall for the 6
I am trying to run a single little wire from near my battery to my steering wheel for an LED which will tell me when the meth pump is running. I have run into a pretty serious problem though. I can't for the life of me work out how to get the wire through the engine bay. I found that rubber grommet behind the battery so I thought I could get in through there. After much cursing and struggling I managed to put a hole or two with a coat hanger, but after it punches through it seems to hit something hard, possibly the firewall (although I am a little worried the bunch of wires :argh: )
Is there a simpler way (preferably with a guide) for our cars without having to drill through? All the guides I can find are for american cars with their LHD witchcraft.
