hi happy holidays
there are no more service manuals it is all on computer.here is some info about high idle switch.
e.c.m connector c1 (blue) pin 71 may have a light green wire in it circut 488 p.t.o enable.as soon as i do one i inform this page.
i see alot of you are running chips or other modifacations.our d.s.m informed us if any diesel comes in chipped and has a engine related problem NO WARRANTY.

Okay, pin 71. Is that the same for all the years, or is the '03 different? Do you add 12+ or ground to pin 71?
