Remove the wire on small terminal #3, and tape up the wire end. Be real careful, as there are other terminals on the relay that are going to be "hot" ALL the time while you're in there with a wrench.
Find a piece of jumper wire a couple of feet long at least. Strip the insulation from both ends.
Put one end of the jumper wire under a ground bolt or screw. Make SURE that it is actually grounded. Remember, a lot of the front end is plastic. If the wire is long enough, you might want to just run it to the passenger-side NEGATIVE battery post to be sure.
Turn the key to "ON"
Touch the other end of the jumper wire to terminal #3, and NOWHERE ELSE!!. Do you hear a click? If so, then measure for voltage on large terminal #4 while touching small terminal #3 with the jumper. If you get voltage on large terminal #4 while doing that, your Glow Plug Relay is good, and you will have to find out why the ground from the PCM isn't being provided.
Likely, that's our next step.

It's two days later.
Guess Tripod musta' got it fixed...
I sure wish some of these guys would come back and let us know if we've helped.
It takes time to write out this stuff for them, and we haven't a clue whether it was worthwhile or not.....

That manual switch is a good idea. One of my next changes, and I'll include an LED indicator, too.
Thanks for getting back to us, but remember, we want to hear how it turns out "at the end", that is after you get the truck back and have driven it on a few really cold days.

i want to mount an LED light in my cab for mine as well but i am noit much of an electrician either . anyone have any 411 on what to wire to what? also, how long will the LED stay on? the whole time the glow plugs are on (i think 1.5 - 2 minutes) or just long enough to initially heat them?
