electrical help

[scbronco]

ok, so electrical is NOT my strong suit... got a couple of questions...

i have been looking at some wiring diagrams on classic, and they dont exactly seem to match my 74...

at the starter solenoid, i have a yellow wire, off the main harness, and a fuseable linke off the Alt Harness, do both of these wires terminate to the positive post on the solenoid? also have a whiteish wire off the alt harness that i have no clue where it should go...

Next question, can i eliminate the stupid ceramic ballast resistor by getting a coil with an internal resistor? will this causeany problems?

last, i have a wire off the engine harness that has no where to go. is this a ground? the coil, oil, and temp are all connected, and there is still one stray wire. its green, but its "new green" so htat may not be the right color. i assume it is a ground, but just want to be sure that the engine harness does have a ground wire...

thanks in advance...
