drg Posted July 14, 2011 Share Posted July 14, 2011 I'm trying to remember on mine I now I wired the under dash lights on the one with the battery. I kinda think my son did the wirering and there was a post in the fuse and breaker panel that turned of and on with the switch. On another post you had mentioned doing an upgrade on your ecm to give you more power at higher elivations just wondering if you've tryed it yet as mine runs terrible when I get into Colorado and Alberta to.

drg Posted July 14, 2011 Share Posted July 14, 2011 Instead of trying to remember what we did 2 yrs ago I should have went and looked at my truck first. Went out and checked mine and there are 2 wires in the fuse panel box on the inside of cab that are labeled. We have wired into one of them to get power with the battery switch. Dennis.

rhasler Posted July 14, 2011 Share Posted July 14, 2011 The battery switch is powered by fuse 61, the stud labeled battery in the dash is powered by fuse 11. The keyed power switch is powered by fuse 30, the stud labeled ignition in the dash is powered by fuse 27. 1 Quote "Mebbe I'm too ugly and stupid to give up!"

However, you cannot go wrong with incorporating a contactor, (relay) in series with your induced loads to take the sudden inrush of current in any electrical system. 10 amperes is not a lot of load but over time the contacts of the switch will oxidize and break down. This would not happen with a contactor coil and larger contacts absorbing this load.
