I'll be installing a Curt hitch this coming weekend, seems pretty simple. My concern is the wiring. I ordered the hardwire kit #118176KIT from etrailer and feel confident that I can do this myself, having installed them on a previous Jeep Grand Cherokee and Acura MDX. Does anyone have any general instructions for connecting a wiring harness on the E70?
I'm concerned with the ECM re-program and have a few questions about that. Where does the error message display (idrive) and can you clear it while driving until the next start up? Does it affect the operation of the vehicle? How much will the BMW dealer rape me for the re-program? Thanks for your help.
