hey, I bought a dc powered 100 watt fuel filter heater that I would like to install myself. From what I understand a typical way to do this is to connect the 12 gauge wire (+) to the battery and run it up to where I want it. My questions are these: what is the best route to take to get it to a place, maybe the middle console, to wire it to a switch, and from there how to get it into the engine area? Once I have the wire past the fire wall I can figure out the rest assuming I can run the negative wire from the heat pad to somewhere in the engine area.

Thanks in advance. Look forward to your responses
