To anyone with a 280ZX Turbo, I have quick question for you that I really need help with! I'm a little embarassed, but I forgot which color wire goes to which side (positive/negative) of the coil! ^^;;; Could someone with a 280ZX turbo please take a quick peak at their coil and tell which color wire goes to which polarity? Turns out the colors are different than the NA engine, so my NA ZX was of no help. And the service manual was unclear to me. Thanks!

 

on my car.. blue on the right.. black/white on the left..

 

So, which is positive and which is negative?

 

black is positive.. blue is negative..
positive on left..

weird choices for colors.. black is usally negative but not alwayz

 

On the NA engine, the Black wire with white stripe is actually the Positive lead. So that's why I needed someone to look at their turbo coil. There's a little "+" or "-" symbol embossed on the top of the coil to show polarity. Many coils also have a colored paint dot on top too.
