1968 camaro, did a bonehead thing. I remover the coil and wires and didnt mark them 2 months ago now cannot remember what goes where. I know the condenser goes to the + and the distributor to the -, but there are two additional wires, one brown from the harness and one blue from a ceramic type buss on the firewall can anyone help me on where they go?
Assuming you are using original style point distributor and coil the other two wires should also go to + side of coil along with radio capacitator (condensor). One wire should be 12 volt cranking from the " R " terminal of starter solenoid and the other 9.5 volt thru resistor wire or ballast resister for on position (running) of ignition switch. I believe this would be correct and hope it helps.
You mentioned two wires. The blue one from a ceramic resistor is the IGN power feed to the coil (+). I don't think you have a factory setup there, since the original configuration used a ballast wire I believe. Larry has labeled that wire white orange/purple in his diagrams. In any event, your blue wire from the ballast resistor should be what you're looking for as an IGN feed.
The brown wire should be for your tachometer and is connected to the coil (-) terminal along with the distributor wire for the points.
You didn't mention a yellow wire. There should be one that connects from the starter solenoid (R terminal I believe) to give a full 12v shot to the coil while cranking.
On a nit-picky note, the condensor is inside the distributor in paralell with the breaker points. The component you mention is a noise filter that gets attached to the coil(+) and is grounded to the coil bracket. It's purpose is to cut down on ignition noise getting into your AM radio.
