Thumper Posted June 30, 2006 Share Posted June 30, 2006 Just got my new project up and running; with details and pics soon to be posted. It is a 280zx n/a non-digital dash running megasquirt and msd 6al. Everything is working to plan except I have no tachometer. I have hooked both the tach output on the msd and 4 other wires coming out of the stock wiring loom to every possible combination with the same wires wire with some sweet sparks to boot. I have hooked up the black/white wire to the - and + terminal on coil, the blue wire, white wire, etc... I think what I'll end up doing is running the tach output wire on the msd to the correct wire right behind instrument cluster. I have never had much luck with wiring diagrams so does anybody know what color and where I can find this wire or did I not try something earlier that should make it work?

DemonZ Posted June 30, 2006 Share Posted June 30, 2006 I'm taking a wild stab here, I think you need a "tach convertor". Quote Link to comment Share on other sites More sharing options...
Phyxius Posted June 30, 2006 Share Posted June 30, 2006 yep, I have the same setup, and you have to have a tach converter. I forget which one it is... I'll try to look tomorrow and see which I have. Quote Link to comment Share on other sites More sharing options...
Thumper Posted June 30, 2006 Author Share Posted June 30, 2006 Ok I thought tach adapters were only for if you can get a signal but it reads way too high because of the multiple sparks at low rpms? I cannot get any movement on mine tachometer. But if a tach adapter converts the signal from one to another so that the tachometer can read it then that is what I need.
