I recently bought a negative battery terminal knife switch and thought it would be great. If I had to work on something I could break the switch to the terminal. Also if I had to leave the truck in a crappy area no one would be able to steal it. But someone mentioned to me that disconnecting the negotiating for more that a couple minutes could be bad for the battery and computer. Is this true I have never heard of this and I am now questioning if I should install it. Please help

Whoever told you that is an idiot.

All the disconnect would be doing is clearing yer radio presets and clearing the KAM in the PCM, hence clearing Adaptive.

No biggie - next time you start yer truck and drive it for a while, it'll relearn.

The ONLY downside is if yer in an emission testing region - a disconnect will set a P1000 code and all of the IM Readiness tests will not have run - could result in a test fail if it's not driven enough prior to testing to complete the drive cycle.

Don't make a daily habit of disconnecting the batt and you'll be fine.

FWIW - it's generally considered safer to disconnect the NEGATIVE terminal.

thank you thats what I thought I just wanted to make sure. I am in an emissions state but I just went through inspections and I know about the 100 miles or so you should drive to complete the drive cycle

Seems to me if you need one of these to prevent your truck from getting stolen you should reevaluate your life.

Ah. Yea, nothing is safe there.

Scums all over. A friend has 3 POS Neons in his driveway. They were all broken into last night.

Out of all the potential cars, crappy neons? Cmon.

better safe than sorry I was also thinking to get a master battery kill switch with removable key but I decided to go with the knife switch in the negative terminal. Thought better to keep it simple

With PATS it's going to be nearly impossible for the average crook to start your truck.
