...F250? My '95 Ford F250 is having problems with starting up in the mornings. I replaced the alternator and batteries, thinking they were dead. So now I moved on to the glow plugs. I have removed half of them, and they do need replacement, which I will do. I wanted to check the wiring for the glow plugs and the relays and such. I want to make sure everything is working well and that current is getting to the glow plugs. But I don't know which wires are for the glow plugs and which relays are fro the glow plugs. So I have looked online to see if I could find a diagram showing all of that to help me, but I have had no luck. If you know of a web site or where I could find a diagram, would appreciate it if you could tell me.
