Hi, Id like to find a switched power sorce near the battery to pwer a relay. I don, t habe any testers so Im wondering what you guys have found? Looking to put ina fuseblock from Eastern Beaver
Find the power wire for the fuel pump? it should be somewhere in that area.
I would be wary of tapping in very close to the computer, if you have a circuit that puts noise into the wire it could mess with the computer.
