Hello All,
I have an AUX batt system and am installing components such as a fan/lights/ect.
Should I run the negative wire back to the 12v fuse block or am I OK grounding it close to the hardware on the bare metal of the van body? It would save heaps of wire if i just needed to run the hot wire. Thanks in advance!
Straight down to ground sir.
With built in wiring, it is best to ground to the body/chassis.
