install electric speedo on 3rd gen?

Hey everyone -

I'd like to install an electric speedo (the gauge, not the underwear) on my 3rd gen - which has a mechanically-driven gauge in stock trim. Thinking about a chain & sprocket conversion, and the Honda qauge isn't the most accurate even with stock gearing.

Checked this forum & the other one, and looked at the parts fiches online... couldn't find the pickup for the 4th gen speedo although the wiring looks pretty straightforward - hot, ground, and sensor lead.

This would also be a first step toward the eventual world domination frankenviffer front end, muahahaha.

Thanks to anyone who can shed some light on the process. :smile:
