Default harness power question...
Got my harness back from speartech last week.
Came with the little fuseblock...was looking at places to mount it, and I was looking at the wires, what they are for...the pcm has a single 12v+, small gauge wire...(not counting ign+ wire)
Is that all the juice it needs, that one wire?
Just wondering if I was missing some larger gauge + wire...
If this is correct, disregard my ignorance please.

PCM doesn't draw much. You have a wire that goes to your power distribution, and a wire that goes to a switched ignition source. Out of it is power for everything else.

The engine including ign. coils, injectors draws about 6 amps at idle. This does not include fuel pump, fans.
