Glow Plug Controller wiring problem

[Tres]

Has anyone run into this. My controller is not wired like the TM shows.

If you look you will see that there are two black wires together and the yellow is by its self.

The TM clearly shows that the black and yellow are together and the one single black is next to them.

So what gives here. Could it be someone changed the wiring on the controller or is the TM wrong?

Your truck is wired correctly. Sometimes there are errors in the diagrams. There are 4 known errors in the TM glowplug diagram.

have you ever seen the GP Theory sticky?

take a look at the attached diagram. The two black wires are attached together.

Ok, thank you for confirming. I am having to wire this up, all of the wiring was stripped out and I am rewiring everything and this had me kinda stuck.
