I was reading through the install guides on the iDatalink website, and it looks like there are at least two splices that need to be made: to the ignition, and to the parking lights. Although, it's a little difficult to understand what guide I should be reading. I chose this one.With the T Harness, they don't need to cut any wires, correct?
I talked to a shop a few months ago about doing this install, and now that it is getting cold I'm going to call them again today. I miss having remote start in the winter.
