I took my multimeter and touched one probe the where the harness connects to a glowplug. I took the other probe to the lug on the glow plug relay where the harness is connected to the relay. I set the meter to Ohms (horseshoe thing) and checked for resistance. I wanted .2 Ohms or less for each wire, and that's what I found.
I have a 89 also and have the same thing, gonna replace the glow plugs hopefully that’ll work but if not I’ll do what you do in the next episode. Anyways there’s a transmission overdrive button?!
If you have the E4OD, yes. Button is located on the panel next to the steering column. If you got C6, no overdrive button as the C6 doesn't have an overdrive. Both transmissions were offered in '89
I made another video that covers how to troubleshoot glowplugs as per the Ford shop manual. In the end though I bypassed the glow plug controller and setup a manual momentary switch in the cab. Video here: th-cam.com/video/KyUMOYllnek/w-d-xo.htmlsi=6PPKw-rQNOK8stIh
How did you check the harness. Thanks for the video

Looks like someone crimped female bullet connectors on the ends of the GP wires... because the OE white plastic ends crumble away.
Most of them don't have positive engagement when you put them on so it was my thought it was a homebrew setup.
You figure this shit out? My 87' does the same damn thing. Wts light blinks and thats it.
