I'm going to have several electrical questions. 1st, Is pin #8, on the 14 pin plug at the relay board, the only switched 12v+ source in the engine compartment? TIA, Kent

The short answer, which is close enough for our purposes:
- Always make the ground wire at least as big as the power wire. If it requires a 12ga wire to power it, it needs a 12ga wire for the ground wire. Note that the body of the car is about a negative fifteen-hundred gauge wire for most of our purposes... (IMG:style_emoticons/default/wink.gif) --DD |
