Wiring an Autometer Tach on 12a????

[Speed Raycer]

How the heck did you guys wire in your tachs?

We're trying to figure it out on our first Gen RX7 and are getting nowhere. We've got a 10,000 rpm Monster tach with peak recall if that makes any difference.

I think you go to the trailing coil for the reading. I know you cut the wires to make the tach read like a 4cyl. put a fuse in line with the power, just in case. rather blow a $.10 fuse than a $100. tach

Thanks guys! That helps a bunch! Good idea Chris. The line is already fused but I may put a smaller fuse inline just to be on the safe side.
