Re: Routing battery cable

A lot of over thinking here.

Batt in trunk>+ cable to solenoid>-cable to frame rail

Batt cable from solenoid to starter>jumper to S term (not for LS)

Purple wire to trigger term on solenoid. (LS starter tap purple and run to starter)

+ wire from Batt side of solenoid with fusible link to terminal block in engine bay, core support or where you want. Alt, ECMs, Car 12v to terminal block.


Large batt cable and purple wires hot only while cranking. If it shorts when you turn the key to start youíll know it. Lol. So I see no reason to try to fuse it. The original 12v cable in these cars were never fused and are hot all the time in the engine bay.

I do not run the heavy batt cable thru the interior of the car as imho this would increase the risk of fire if for some reason it did short being things like carpet and other interior components are in close proximity to the cable.

I run it straight down through the trunk with a grommet and underneath the car to the front seperated from the fuel line and other wires. This way if it were to for some reason short thereís nothing to catch fire. Also easier to inspect the cable for damage than if itís hidden inside the car.

You're welcome. Whatever you choose, you want it to be safe. I as well as plenty of others are not overthinking things in that the addition of a proper protection device such as a fuse or circuit breaker to a wire or cable at the source of power is a good thing. Just like in my home, I'm real glad there are fuses or breakers in the proper place.
