I'm wondering what color on the stock coil pack is positive(+) and which is negative(-). This is how I think it should hook up also, (this is a 6AL unit with the SS coilpack by the way) The white and red wire from the unit will be connected to the two wires going into the stock coil pack and the orange and black goes into the SS coil pack. Is this how the rest of you hooked it up?? Thanks for any info on this guys...

Oh this will go into a 93 240sx by the way.

Reason why I ask is because I want to get it right the first time and not reverse the polarity and screw something up... thanks again guys.

That hook up is correct. Black and orange to the coil pack (orange +, black -), and red will connect to the Black/red stripe and white to the green/black stripe. If you have a factory tachometer, i believe you will need their tach adapter as well. I did on my 90 coupe. Then the red from the box as well as the tach adaptor go to the black/red stripe, and both whites go to the green/black stripe. Good luck!

Thanks JNM240... and those who "viewed" the post.
