I just installed the G2 following Yeti's guide. Big thanks to you dude! Glad I wasn't the first to attempt this. Managed to save the heaters. A couple of minor changes, I put heat shrink over the throttle tube to minimize the heat sink effect prior to heater installation. I also carefully removed the offset slider from the wires, cut at that location, slipped small diameter heat shrink over the wires to the grip and soldered and shrinked everything up. (should have taken pics).
Very pleased with the results. A slight loss in grip heat but well worth it.
Thanks, Mach Z
