Default Where's a good 12v source under the hood??

I'm wiring up some strobes in the headlights for show. I need to find an always on 12v source under the hood to splice into. Where's a good one at, or how can i find one??

Uh, try the battery. Just have the positive wire fused and switched. Simple.

/\/\ the transformer is internally fused. I tried wiring to the battery already but it was just too hard to hide the wiring.



Anyways, i used my trusty test light and found a source!! I had previously thought that the headlight wires weren't hot unless the switch was on. The test light told me otherwise. I spliced into a wire there, and ran everything else:


SUCCESS!!!


Mechanicly inclined i am, electrical i am not, haha.

You could also have just connected it the the wire feeding the fuse block. Good chance you might not have needed to splice anything.

Not good to splice into wires and draw current off of them like the headlight wires. This could cuase further problems becuase hte wire is a specific guage for powering the headlights and if your drawing current off of it you could mes the headlights up. I would recoment running 1 8 guage of fthe batter to a distrobution block that you can cleanly mount somewhere in the engine bay and also have a few extra spots to add things later.

even though the wiring for the strobes are significanty smaller than the headlight wire i spliced into? Also, the headlights + strobes will never be running at the same time. The strobe circuit is a normally off circuit.

I'll be adding undercar LED's this afternoon, would you agree that it would be better to splice into the LED's power lead rather than the headlight?

for those i would go right to the battery....or go through the firewall into your dash and use the "add a circuit " method into one of the existing fuses
