Nope. I was pissed I unhooked mine. It reset my hour meter.

The switch is not powered. It only changes voltage resistance. It doesnt matter which wire goes in what hole either.

You will never hurt anything by removing power from the batteries...Unless of course you reverse the cable on the reinstall

Kyle, in the help menu once you open up EFI there is a tutorial. It does a pretty good job of explaining how to wire the switch in.

I'd unhook the batteries just as a precaution, it's only your engine's computer, and only a few hundred to replace right??? No big deal to fry it :D Not like it's that hard to unhook em anyway. And we've never had a trucks hourmeter reset, or anything reset for that matter :confused:

well i got it on..took a lot longer than expected...the plugs would not unhook from ECM so i unbolted it so i had better angle at it!
and before i put everything back together i put batteries in and tested to make sure it worked! thank god for the scan tool! only bad thing is one of the pins broke off..but that is being used for the ground somewhere in the truck now

thanks jesse ive looked at that one but since they show blue connector it confuses me..i found one that Nick at duramaxtuner did that i used!
it was easy just time consuming because the plugs were all stuck

i think the only way you can do is by unbolting the ecm... which isnt a very big deal...
and you broke a pin off :eek:
