New here have a 2002 F250 powerstroke I'm having issues with my glow plug solenoid the person you had it before th did a real hack job most the wires are cut lot of the wires underneath the hood are cobbled together I'm just trying to get my glow plugs work now does anybody have a diagram of what wires what any help is much appreciated!

 

 

It's it's turned on California truck Scott the old solenoid there with one wire attached to it a new one mounted in place and all the ends of the wires cut off taped up!

 

 

There are two relays there. The front one is Air Intake Heater (AIH). Most of us have removed the heater and left the relay in place. The other relay, the one pictuered, is the glowplug relay.
