If their is extra wires it would be a distributer for computer control (ECM) I think

 That was my first thought, but the later ECM type distributors have a second harness with multiple wires in it that connects to the ECM harness. The one in question here apparently only has two single wires "extra". Need to know where each of them originate...
Wonder if the grey wire with the male plug is for the tach filter?

Geez, don't get fired, I can't afford to pay your salary. Spent all my money on the distributor.

I'm not the one he's worried aboot! 

I see the pics now...btw, they wouldn't load here because of the size.

  

Here's the skinny on the extra wires, from the GMPP specs page that includes that part number. The wires are for a ground, and an extra tach output. I would tape them both up, and tuck them out of the way somewhere. It wouldn't hurt to actually use the extra ground, tho.

Thanks Joel for the time you spent researching this data. Answered my question and more. I'll keep you updated how the new cap and rotor does on the old distributor.

UPDATE:  It's been ten months since  I switched to GM Delco distributor and not one "no start" conditions. Put about 4,000 miles on it from last June till now. Old blue didn't get much rest this winter. New A/C works great. Getting ready to put cruise control back on it.  I get looking at the scenery and have mopeds pass me going up a hill. Been talking to Rosta and will probably go that way. Aggravates me when a 2015 something on the interstate goes from 40 mph to 70 mph and back again every mile or so. Don't want to be that somebody on the interstate. Wife does look like a cute little bobble head when I do slow down and speed up. She doesn't think the soda straw in the nose is funny though. Thanks again for the advise.
