Default electrical issues

I need help from some of you electrical guru's. The wiring on my truck was all Bubba'd up (southern talk) and I decided to replace the entire wiring harness. I bought the Painless kit #10205, and working on getting it installed. There are some wires from the diesel area that I do not know where to put them. I have included some pics so I hope that someone can help.

This picture is the connector for the glow plug control switch on the back of the 6.2. Both the wires have been cut. The white wire is in slot 2 and the black in one. According to the Haynes manuel the white should go to the glow plug relay and the black to system voltage. Where do I hooked them up on the painless kit though?

This is the plug that goes to the water sensor on the Stanadyne Model 80 secondary fuel system. There is a yel/blk wire, a pnk/blk, blk and purple. the purple goes to the fusible link in my hand and then to a red. This has been cut and not sure were to put it.

These are all pnk/blk wires that look like they are all connected to two other wires that were cut. It looks like the three of the wires are going to the fuel wire seperator and one going down the back of the motor. I am not 100% sure on where the cut wires go.

Any help will be greatly appreciated.

It don't look like the pictures went through. I will see what I can do and get them posted.

Crazy, I have the same thing to follow, but the trouble I am having is what to attach these to with the new Painless wiring kit.

I found out the hard way, painless is a pain in the a**. Do you have a wire diagram for your truck? That will help you determine where to run the extra wires

I do have a diagram but it is figuring out what wire from painless to use without screwing something up. I know that you need a hot and ground when it comes to wiring but very little after that.

I believe, and somebody correct me if im wrong, but your entire harness is already grounded out. How many wires are left over from the painless harness? Are they labeled?

The one wire that is left is the coil wire. Prior to ordering this harness I did call painless about using it in a diesel and the tech said that it could be used with the coil wire being used for the diesel power wire. That is all they said.
