cgsheen Posted February 28, 2017 Share Posted February 28, 2017 Still using a single coil for spark? No one is going to know the answer to your question without knowing the particulars of your "standalone". The 260Z Tach works off the "pulse" that causes the coil to fire (you'll notice that the blue "tach signal" wire is connected to the "-" coil post and the output of the electronic ignition module through an inline resistor in the stock configuration).

JSM Posted February 28, 2017 Share Posted February 28, 2017 You can use this link as a reference. Green is switched positive, black is ground and the red goes to - side of coil with a resistor. I happened to have a resistor from a ZX I just pulled. Now your 260z tach may be different, but you could always source a 280z tach. http://www.zcar.com/forum/10-70-83-tech-discussion-forum/110246-280z-tach-wiring-point-me-right-one.html#post767501 I just did this for a tach I sold: https://youtu.be/B3-KYS74FF0 Quote Link to comment Share on other sites More sharing options...
kubus Posted March 1, 2017 Author Share Posted March 1, 2017 ok - my bad... the car is fully rewired / new standalone EMU ( same as hal tech / megasquirt ). coil on plug setup. Quote Link to comment Share on other sites More sharing options...
JSM Posted March 1, 2017 Share Posted March 1, 2017 You have to dig in the FSM and see how the 260z tach is wired. If it is the same you can hook it up like I showed you above. You'll need a reference I would think from the ECU for the tach signal. Quote Link to comment Share on other sites More sharing options...
