That's a good point you made, PT. Although, lots of people have DEI alarms, most people don't have the same installer do it in the EXACT same way. The factory has to for servicing reasons. I've never moved a factory alarm brain (in fact, I don't recall ever having to even work oonn one), so it didn't occur to me to do that. I'd say that mitigates a lot of my security concerns with the bypass kits. Also, we have to keep in mind that the bad guys won't know whether the alarm is a stand-alone unit or a bypass kit using factory wires.
Only having to make four connections for an alarm install is great! The only drawback is, the time you save on installation is going to be subtracted from the cost of the bypass kits and programming modules, is it not?
This is probably asking too much but, do the bypass kits allow for remote start installation without having to run an injector or tach wire and without a VATS or PASSLOCK bypass?
