Hello I have a 93 f350 with the e4od, so the light on the shifter does not work? I do not know why, but when I press the od button it does down or upshift so I know the switch is working how can I fix it so it will light up, especially if something is wrong with the tranny I will not know due to the light being dead, also I don't know if this is wired into a harness with the parking brake or something, but that light also does not appear on the dash when engaged, although when cranking the parking brake light will show, OD does not. Please point me in the right direction guys, fuses have been all checked even the good ones, replaced for overkill lol, also power distributer fuses have been checked aswell all check out good, thanks
