Jason81NA,82RBtt Posted December 10, 2003 Share Posted December 10, 2003 I'm need some help hooking up my new Apexi ITC. Here's my set-up I'm using a SDS with only fuel control, with a 280zx NA distributor. I also use a HI-6S to retard the timing under boost. Here's the problem I need a postive and negative digtal tach signal. I know that the Turbo computer uses a distributor that has both of these, but I can't use just a distributor without having to hook-up the turbo stock computer. Let me know if there is a simple way to convert analog signal to a digtal one. Also what is the voltage of the red/green wires that connects the NA's black box to the distributor. 12V or 5V?? Thanks Jason Quote Link to comment Share on other sites More sharing options...
yo2001 Posted December 10, 2003 Share Posted December 10, 2003 I belive it's all 12V analog signal, even to the ECU. Quote Link to comment Share on other sites More sharing options...
