Had some time to install my Sprint Booster tonight.
I removed the two 10mm nuts to lift up the pedal to get a better grip on the connector. You probably don't need to do this, but it makes it easier. I had the tools so I just did it.
Snaking the wire around without taking the dash apart took a little time as I didn't want the wire in the way of my big feet.
I settled on cutting a groove on one switch panel for the wire and attaching the controller to the switch panel just above it with a 3/4 inch velcro dot pair. 1/2 inch dot might fit better, but that's what I had on hand.
I felt it would be the easiest way to install it without a lot of bending strain on the wire. (I could be mistaken about that.)
Had to grind a small channel in the dash above the switch panel too because it pinched when you press the panel back in. I should have gone deeper into the switch panel with the notch. The wire actually hides the channel so it's good until I rewire everything someday.
All easily done with a Dremel tool. I'm sloppy so I got a few nicks here and there. Luckily nicks don't bother me too much. Go slow and try to minimize that kind of thing.
Fired it up and all worked well. Race 5 (default) is sweet. Sport 5 (default) didn't do much for me, so I punched it up to Sport 9 for starters.
Gave it a test drive around town and on the highway. Race 5 downshifts quick but I suppose that's what you'd want it to do.
Anyway, that's my initial report. I'll play with it for awhile and see how it rounds out.
