b2200 ignition wiring

Help.
I got an 87 b2200 from a woman who had run out of gas on the interstate. She let it sit a couple of days, when she took gas to get it, the wiring harness on the driver's side was cut and gone along with the coil. I have replaced the coil and run new headlight wiring. I need a wire by wire start and end point for rewiring the distributor and coil on this truck. It is carberated, if it matters.

Welcome!

Sucks that people will do something like this......she must have left the truck unlocked I guess? I definitely wouldn't have left it sitting on the side of the road any extended amount of time.......that's asking for trouble & expense!

Anyway, here are some pics I have of the coil area......maybe you can see what color wire goes where.....

I wondered if it wasn't a grudge thing or a really delicious owner's jilted honey?

Is the y/bl wire important or necessary? I see this is sorta like old GM's right?
IS y/bl tach lead?
