Running wires through firewall and engine kill switch
Hello all, I'm trying to run a couple of sets of wires through the firewall, and wanted to see if anyone had suggestions about the best place to push through. I can't seem to verify any access from the inside or from the engine bay. Suggestions?
Also, I'm trying to hook up a 14 gauge, 20 amp, 12V DC circuit that is energized only when the power comes on in the car. From there I'd like to have a switch to turn on my hydroxy cell. This way, if I forget to turn the switch off, I wont drain the battery.
I was originally going to hook it up to the stereo ACC but the wires are 18 gauge. The max I'll be running through the wires are about 7 Amps. Ideally i'd like to have the circuit isolated from the fuse panels, so I guess my question is where do I splice into the harness without overloading a circuit?
Lastly, I'd like to wire a kill-switch to my engine, which the Kragen guy suggested I wire the switch on the negative side of the power. Thoughts? Best place to splice in again?
I have a service manual on it's way but i'm anxious to get this project going!
Thanks!!!
