Was a seamless install as I have a wireless soldering iron and heat shrink. Got it wired into the PTR ethanol sensor that I already had for my E-85 conversion, so no need to purchase an additional sensor. had to extend the wiring obviously and run that all into the dash, which was a decent amount of work as expected but so it goes. sent the wiring down the fender as the ethanol sensor is usually placed on the drivers side by the battery. then from there into the cabin behind the fuse box (GR/GV chassis) there's a grommet for the hood latch and wiring cluster. pretty smooth all in all. Of note, this ships from the producer, so shipping took like 10 days, so my anticipation had to be patient.
