the contant power cables go to my car alarm, led lights, siren, power locks, power windows, and alarm bypass... they are very small thin awg wires... the ignition and constant power cables under ignition housing are alot thicker... is this possible with no problems?
confident, you're able to do this. make beneficial each and every capability twine has its own fuse close to the battery. Addressing the different solutions: this won't drain the battery any quicker than working a single twine to a distribution block; and there isn't any might desire to characteristic a 2d battery except you intend to play the gadget for long classes without the engine working.
I wouldn't tap into any wires where your alarm is.. If you have any issue, it could arm your alarm, and you might not be able to start your car, until the wiring was fixed...
