What harness did you delete? GPC Glow plug controller?
From what I read on a random google search wiring diagram the power wire for the GP light is a black/ppl wire with a 20a fusible link. The only way I see for it to be lit is if that wire maybe got put on the wrong side of the solenoid.
The light is constant grounded and is powered when the glow plug relay is engaged. The only thing I can think of is an incorrectly placed wire.
I took out the stupid factory international engine harness, all of it. Nothing hooked up to glow plug controller (don't want it killing my new plugs).
I have 4 wires hooked to the glow plug solenoid, each running two plugs. The fuel solenoid, cold advance, and high idle are run off of one key switched wire (cold advance and high idle are on the factory temperature switch).
The overtemp light switch and temperature sender are hooked up the factory way.
Oil pressure sender is mounted to the firewall and uses the factory wire (never seen it on the firewall before, looks factory).
This is the way it was in the 85 truck. Everything worked and the wts light came on when I would run the glow plugs.
I'll have to crawl under the dash and see what is going on, im thinking someone spliced into the wts light and it's getting power from somewhere.
I know for a fact that the black/purp wire that goes on the solenoid isn't hooked up yet.
I've never owned a Haynes or Chilton for any vehicle. I used to use the Michigan Chilton library if I really needed to, but always had jeep FSMs.
I can't get into the Michigan stuff now, they have locked it down and you can't get Into it with just a random Michigan DL number anymore.
Haven't found a Ford FSM PDF.
