I searched to see if you should disconnect the battery before an install and it is about 50/50?.So should you or not?Won't you fry stuff by connecting wires that are live.Is it better to do it and how do you find out if your vehicle will need to be reset if you do disconnect it(without actually doing it)

You should disconnect the battery. If you do the install correctally you shouldnt fry anything, but why take the chance?

I have yet to disconnect a battery putting an alarm in. How are you supposed to test things with no power in the car?

Can't you test and label your wires then do your connections

Most issues are w/ incorrect wiring of systems and a disconnected battery provides no protection, once reconnected you are all done.

A DMM, common sense and a few inline fuses are all you need. A disconnected battery resulsts in reseting clock, Radio (some may need codes to get back,) etc.. Never mind a pissed off customer if they did not know and have to reprogram anything.

Like cntrylvr79 stated, how can you properly test the wires? Just my opinion.

Well I read on here that my jeep ignition harness unplugs so it is easy to do connections and I was just wondering if plugging it back in live would hurt anything,My buddy installed a performance chip into his car but never unplugged the battery and it started smoking.

There is no reason to unplug the the ignition switch in a jeep liberty. All the main ignition wires are easily accessed without unpluging anything.
