The conversion circuit I used I found on a Megasquirt forum. It outputs a pulsed +5V signal.This is the page I found:http://www.aaroncake.net/rx-7/megasquirt/buildingandmodding.aspLook for the section titled "2nd VR Conditioner Circuit" - it uses a chip designed for exactly this purpose. I was able to get everything from Digikey for about $12.

Do I need to shield the signal from the sensor to the dash/cluster? I may be asking a lot but do you have a parts list from your Digikey order? I'm good with soldering(I replaced the transformers in a flat screen TV recently) but in-depth knowledge of component specs/calculations is outside my comfort zone right now.Rich
I saw an old friend the other day that works for ecs he said stay away. if not crappy parts they just have horrible bussiness practices.
