No power to anything

Ok, I posted some pictures I hope will help with this mystery. Look in my gallery for the Pics, golver's 81 V20.

Wire 4: Under dash
1) Cut yellowish wire
2) Where the wire was cut from
3) When plug is seperated, yellow wire prong is missing. looks broken off.

I am thinking the issue is celinoids. The wires running to the celinoids in picture WIRE1 (line#1&2) are live, but nothing comes out the other side of the celinoid. Items hooked up to the celinoid do not work.

I beleive the celinoid on the left is for the trim and may be a Ford part, the other on the right runs to the starter and may be a GM/Chevy part.

I can not, for the life of me, figure out where the purple wire goes. It can be seen in pics Wire1, 2, & 3.

The starter switch is ok. I ran a wire from the bolt on the starter, pic: Wire 3 (line#2), to the Solonoid post on the starter switch. It turned the engine when I turned the key.

So what do you think, celinoids are the problem, no?

Pic: Wire 4 questions.
Do you think this is the yellow wire that runs to the starter celinoid? Does it have to run through the (Line#3)plug, since the plug has a broken prong where this wire runs in, or can I just splice it past the plug? Where can I get another plug for it?
