Ignition coil wires

[78 280zcar]

Which wire goes where :stupid: , I disconnected the old coil and forgot to label them it is a 1978 280z. Does the black white wire go to the + terminal or does it go to the - terminal. Thanks in advance

If it's the same as a 240Z then the black/white wire goes to the positive terminal and the black wire goes to the negative side.

Mine has a black with white stripe wire and a blue wire. Thanks

I'd forgotten that I have a Haynes manual that contains a 280Z wiring diagram. It's really hard to see without a magnifying glass but it does show a blue (L) wire that goes to the resistor and then continues on to the negative terminal.

So if the blue wire goes to the balast resister then that one goes to the + terminal, hopefully. I have a chilton manual that has a wiring diagram but it doesnt really show what terminals the wires go to.

which brings me to another question. Is there a balast resister on this type of ignition. I know the 75-77 have them but it says that there is one on mine in the chilton manual wiring diagram but I cant find one anywhere in the engine bay . HELP. I just bought a Crane fireball ignition coil and it came with a balast resister and I dont know if I have to hook the resister up or not. Thanks in advance.

Nevermind about this post. I forgot I have a factory manual on CD-rom. :stupid: . I feel so dumb right now. And no there is no resistor because it has no points. Thanks for the help anywho.
