Have to ask an obvious question here - did you get the LED to work at all? Do you have the polarity reversed? - an LED will only work one way. Probably need to put a multimeter on the GPR to see exactly what is happening.

Where do you have the power lead from the LED going?

I grounded my LED in the dash area, near the LED. Then I ran a single wire (Orange one) to the GPR for the 12V Power. I hooked this lead to the post going to the GP's. If you are getting power off of that post it should work. Did you verify the LED works?

Do you have the polarity reversed? -

mark i thought all leds were polarity sensetive but this light (dorman 84926) said just one wire to ground and one to assy and no marks on light about this side is pos and other is neg. so i just hooked it up . so i just pulled light out of the truck and used a jump box to to light first way no light thought mabey bad light hooked other way and it worked took back to truck hooked up other way and wa la she worked . so at least im not second guessing my electric skills . and i was thinking im reading ground thru the glow plugs . sometime i feel like a idiot but at least i get it eventully . thanks for all replies guys wes

yea thanks , even though it was a simple thing nice to move on now . for over twenty years of wrenching i never had a resource like this ive only been here reading a coulple of months and have learned a lot about the 7.3 . and i always think 2 / 3 / or 250 heads are better than one . now im going to dive into the valve covers and change glow plugs / uvch / 50 cent mod / ccv / new boots / i have been pluging my truck in for 7 or 8 years every winter want to see if i can unplug for ever!
thanks wes
