I have the one wire hook up as well, and just did a way with the
regulator all together, didn't need it since I rewired new 10 ATO fuse
box, and 4 relays into wiring harness, and the alternator has internal
regulator.
With ignition on, engine not running, light on, engine running light
off, if idle is lowered and alternator not charging enough, light comes on.
This is GM 1 wire from JCWhitney, 60 amps, chrome, and cost $70, no core
charge.
