General Motors Externally Regulated Alternators
The two remaining wires, a 14 gauge black/red wire printed #995 REGULATOR
BATTERY POWER and a 16 gauge black/brown wire labeled #914 ALTERNATOR
EXCITER, will connect to the regulator.
Route the two wires of the Painless harness to the connection point on the
regulator and cut to length. Strip ¼” of insulation from both wires.
The factory 2 pin alternator connector and 4 pin regulator connector from
a factory GM harness can need to be used. Due to a lack of usage by
most customers these connectors are not included with this Painless
chassis harness. If you do not have these connectors, they can be
obtained online, at a local auto parts store, or you can use the loose piece
insulated terminals in the parts kit to make connections.
Connect the black/brown #914 wire to the “4” terminal on the regulator.
Connect the red/black/#995 to the “3” terminal on the regulator.
Two 14 gauge wires which run from the regulator to the alternator and a 14
gauge wire for a ground will need to be provided by the installer to finish the
connections. These wires are not in the Painless harness.
Connect the “2” terminal on the regulator to the “R” terminal on the
alternator. This was a white wire from the factory.
Connect the “F” terminal on the regulator to the “F” terminal on the
alternator. This was a blue wire from the factory.
The last connection will be connecting a wire from the “G” post on the
alternator to a chassis ground source.
