How to add an aftermarket tach to a Smart Car

[High Side]

I like this tach set up. While the smart is not a racer; it is an opportunity to express individuality. If I had any mechanical talent at all, I would add the pillar pods shown. Too cool!

Thanks for the complement, I really appreciate it.

That's really a KOOL set-up!
Does anybody know how to hook up a 450 tach to a 451? I got one thinking 'I can do this' and found out the 451 only has 3 wires (smart buss) and the 450 has 5 on a connector and a flying lead.
Maybe this wasn't such a 'smart' idea after all.
Help!

Nice work! Good on ya for being unafraid to tear into your smart and put it back together.

Yep 13:29 to the Ferrari's 13:40 in quarter mile if its legit. Personally I thought the Ferrari could do better in quarter mile.

Does anyone know which pin the obd11 connector is for the tach? I am still messing with my glowshift tach install. Thanks.

I'm not sure, but if you put an oscilliscope onto the obd2 pins you'll see which one is reading a pulse per revolution.
