Our Mr. Amp comes with a new three-wire plug. We followed these simple steps to wire up our Mr. Amp.
a. Yellow wire with White stripe: connects to the positive post on the back of the alternator. We looped this wire over to the threaded post where we attached our main positive battery cable.
b. White wire with Black stripe: Connects to the single solid White wire pigtail that we plugged into the alternator.
c. Green wire with Red stripe: Connects to a 12-volt ignition source that is "hot" only when the key switch is on. Note: If you have an idiot light on the vehicle, this wire must be connected to it for the light to function.
