Hi, I was wondering about the computer located on the inside of the trucks driver side fender. If I unplug it will it mess anything up?

 

Well unless there are bypassed, some items screwed up would be...

A/C, Cruise control, Alternator charging, Overdrive (automatic), Tach (if using factory harness).

PS. Fill out your signature with truck info, for more accurate assistance.

 

Thank ya

 

you have a engine light bothering you?
