catcher i was looking at the wiring diagram you had, and can someone please tell me where is the wait lamp latching relay & the after glow relay. the reason im asking is because my glow plugs never worked since i bought the truck, and on the drivers side of the truck in the corner of the fire wall and the fender there is a plug that looks like theres supposed to have a relay pluged into it but theres nothing. does anybody know what goes there?
Got a photo by chance?
Does the truck have A/C?
I'm more of a 7.3 guy but have been getting more time on the 6.9's
Here's what I've got.
The wait lamp latching relay, should be under dash near diesel warning light module (contains wait, water in fuel, filter lamps) Part # E3TZ-12B536-A.
The after-glow relay, should be mounted in front of or near the right hand battery on fender. That part number is E2TZ-9C972-A.
The easiest way to check to see if the GP's are working are by using a 12v test light to check the GP's individually while still in the socket. Just undo the connector, place the test light alligator clip onto the positive side of the battery terminal and touch the test light to the connecting tip of the GP.
If it lights it's good, not...bad.
Chances are the controller may be what has taken a dump, course the most expensive of the parts.

http://webpages.charter.net/idi_diesel go to Diesel Information then check out "Glow plug and controller analysis 1993" as he has a wiring diagram there, may be what you need.
VERY nice site, have it bookmarked as well!
