1987 B2200 update and a few questions

k, So I've had it for couple months now. So I thought I'd add some pictures. I've got the entire front end kit coming. bought on ebay. everything is worn out, so I'm gonna do it all cheap now then replace one at a time as the ebay ones wear out. Just easier that way. Also, got pacesetter coming.
Ok, here is my question that I can't figure out! What wires should be going to the (-) and (+) side of my coil. Something is not right!
Tint or no tint? opinions?

Thats a nice looking truck. I hate tint.

(+) side of the coil should have a switched hot from the key switch.
(-) side should have the lead from the distributor. It can also have the tachometer lead connected.

There may be other wires connected, but the above in blue is bare minimum to make it run.

I don't know how Plano summers are, but here in Vegas, tint is almost a requirement!

Here in Plano, Its hot, but the a/c is not working, So when I do the header all the A/C stuff is coming out. Therefor, Tint will be only for looks because windows will be rolled down. But it can also prevent heat from building with the solar block stuff.... IDK

Does anyone have a yellow and blue wire, (or yellow and green???) that hooks to one side (-) and feeds through something and comes back to other (+) side? I'll get a picture in the morning. Its close to the coil.

That's half the reason I know somethings wrong. My tach only works on (+) side

Also, sorry for the large photo. IDK how it happened.
