MSD recommends installing it as close as possible to the coil and says NOT to mount in the glovebox. i guess cuz of heat.

I don't see how running the wires through exisiting holes in the firewall would interfere with the other wires that are there. I don't think you'd have a problem. Can't water splash up into the fenderwell & drench your MSD when driving in the rain or going through a puddle though?
