I have a feeling this has been asked before, but I didn't find anything in the search.
I want to do a stealth install on my 9500ix without hardwiring it. Is it possible to use an extension cord to connect to the smart cord? If so, what type is it? It looks like a land line telephone cable.
I'd route the cord up the a-pillar, out of sight, to the mirror area, where the detector is.
