Putting together from boxes of parts. i have the assembly manual and all the pictures show the regulator on firewall. But all the wiring I have seem to lead me to the regulator on the passenger side fender well. is the GMC different from the Chevy's in tne manual? I do not have any of the sheet metal on the truck except the cab. | | | | | Joined: Jun 2005 Posts: 4 New Guy | | New Guy Joined: Jun 2005 Posts: 4 | Our 57 Jimmy 100 has the regulator on the passenger inner fender, not on the firewall. The truck has not been modified.
