I just installed a Stewart Warner Tach into my dash. After about an hour worth of work it fit perfectly even using the stock plastic bezel and lens...just like stock..well, pretty darn close. I may be a bit biased but its this most "original" aftermarket install I have seen from an off the shelf unit. The only thing I need to do is paint the needle white. I will post a pic or two shortly.
The tach is working but reading 1/3 the actual RPM. It has pins to adjust the reading and per the SW instructions I need to obtain a 9PPR (9 pulses per revolution) Currently it is set on 3 PPR but I cant figure out how to set the pins for 3x the reading......
Anyone have luck with this .....or should I go with that Gizmo off summit racing
