OK, Blk/Yel is (-) Brn. is (+) and the grey is (-) for the tach.

Ordered a new coil today. Ballast ohmed out good at 5 on the top and 1.5 on the bottom. Found some bare wires that possibly touched the intake manifold too. Re rapped the wiring harness there too. We will see. All other wires on engine, connections on firewall and under dash and steering column looked good. Thank everyone.
