Yesterday I installed Off Road Engineering's (http://www.offroadengineering.com) HIC600 throttle controller in my LLY and I'm impressed. Install could not have been simpler, it functions perfectly, and it fits my needs to a "T" (origin of that term?).
The only connections to OEM is a tie into the OBDC system (tapping +12v, Grnd, and buss leads) via a very compact connector and a (separate) ground and/or +12v key power. Options provided are up to three user-set fixed rpm settings engaged via SPST switches, an automatic rpm increase when battery discharge is detected, and/or verrry fine rpm control via a potentiometer.
Since it is already the case that I have tied into the ECM and BCM in so many places that mention of warranty would cause any GM service manager to break out in hysterical laughter, I chose to hard wire into the OBDC leads, with the buss lead switched at the console to effectively engage/disengage the controller. With the buss disconnected, it assures that a Tech2 won't get confused.
A second SPST switch at the console can bring up the rpm to 1200 (to keep a 3KW inverter happy) or a variable potentiometer in the rear of the vehicle can be used for fine rpm adjustment (to control a Premier welder voltage).
I purchased the unit through Yawan Smith (408) 591-1029 who provided the switches, pot, wires and connectors.
