Glow plug cross over and??

[SAVAGE77]

Doing head gaskets... blah blah blah.. Ok, I've found the cross over wire from one glow plug bus to the other, no brainer. However, I cannot find Any wire in the harness or from the glow plug controller that makes either bus live in the first place. Does anyone have a picture of this wire or know how it runs? I'll never let anyone else work on my truck again I can promise you that.

the wire comes from your gpc to the back driver side glow plug

two wires go on the left bank, one wire goes on the right bank. longest left side goes to cyl 2 glow plug, shorter left side goes to cyl 8 glow plug. long ass right side goes to cyl 1

I sure can't find the one from the gpc controller to the #8 cyl.. Any pictures? I can't imagine that I would have removed it completely..
