Switched 12v source

Gents, the Sniper and FiTech, require a constant 12v to drive everything, fans, fuel pump, ECU/ECU memory, etc. This should be 12v power coming directly from(and buffered by) the battery. They also both require a KEYED 12v source. This is simply a trigger wire for the internal relays. You want the power as clean as possible to prevent any interference(RPM Noise).
