Glow Pulg relay question?

[stock]

Hey Guy's, I just checked my GPR and once the ingnition is turned on I have no power going to my glow plugs. This is after I have switched out the old GPR with a new one, the only thing is the store(NAPA) did not have the 110 GPR on hand, they had an older starter relay made for an older 90's ford that he said would work. I swithched them out as they appear to be that same only a 90 degree difference in the mounting.

I tried to start the truck, and no power to the plugs. I am not sure what to do? Do I have to change to a 110 GPR? I have power coming into the switch on the big line, and one of the little lines, bit no power to the yellow black, or the other little line.

Is it maybe the computer not telling the GPR to come on. Do I possibly have the wiring wrong?

Any help you have will be appreciated.

You need the stancor relay. Check the batteries glow plugs use a lot of juice. I can't say if its the computer or not. Either way toss that stock relay and whatever napa gave you and get the stancor relay you will never have starting problems in the cold.
