It does work inside a building. Distance? Just a guess here. Sometimes my inch is a mile and other times it is the other way aroundWhen you say 'the same range' - can you give an estimate? Does it work when you're inside a building and does being inside significantly affect the range?

It’s seems brad has a harness
I have to believe that even if there is only one end that plugs into the module for the remote start and bare wires on the other that those bare wires cannot be run back to the source instead of spliced into a wire. There has to be a source where those wires come from. I think "splicing" is the easiest way to do it and believe most installers will take that route, but doesn't necessarily mean it has to be done that way. I am by no means an expert but having dealt with HMI,s (Human Machine Interfaces) and PLC's (Programmable Logic Controllers) a lot you do not want to splice anything for the cleanest connections. It may be a pain and take longer to run a new wire to get back to the source but it can be done. You can use Molex connector kits, like shown below, which are very easy to make and can be found in just about any configuration you need. That may be considered a "splice" but if it is then most of the vehicles have "splices" all over them anyway. Ok, I will get off my soap box now and feel sure there will be something out soon to make everyone feel more comfortable about this type of installation. After all it is a new car and even if a splice does hold up for the entire life of the vehicle and you are always thinking it may fail then the new vehicle will never be right with you. Mine is working great and didn't see them splice into anything (doesn't mean that didn't) so I am happy with it and feel confident it was done right so am enjoying the key fob remote.Got a follow up email from the Viper dealer...
"To give you more info. The remote start harnesses are never plug and play for these vehicles. There is always some wires needed to be spliced in."
FWIW - could be their way of trying to convince me to come in for their $50 off special thru Sat...
Two sources also indicated the range for remote starting the car with the 3X-lock from the OEM fob is limited to the same range at which you can lock your car (makes sense if it's 3X-lock that starts it). Not sure how far that is... need to test it I guess...
IMHO - probably a good idea to wait a while and use the free app in the meantime...
