Denso GM 4 Pin Regulator/PCM Bypass

This is a 14.8v set point regulator with a plug for converting a pcm controlled unit, to 14.8v, 15.3v or 15.8v with a ignition source, or replacing a unit in your alternator. The 15.3v and 15.8v variants use diodes inline on the sense wire to bring your setpoint up.

This is for Denso Hairpin type alternators only, this is something most people are capable of doing with basic hand tools and a soldering iron.
