280zwitha383 Posted February 4, 2006 Share Posted February 4, 2006 Do i use the blk/wht wire from the original coil Yes, also use the white(?) wire for the tachometer. It's the exact same wiring. You might be pleased to find that you don't have to wire a resistor inline with the negative (tach) wire. I bought a resistor like JTR said and my tach wouldn't work at all so I took it out and it worked fine (this is only regarding ZX's). Of course you will still have to calibrate it on the back but it might work without jumping. 4 years is crazy. It's exciting to hear that you're getting close.

Guest jonnyoldsmobile Posted February 5, 2006 Share Posted February 5, 2006 I am using all autometer gages so the tack will not be a prob. Quote Link to comment Share on other sites More sharing options...
