Ive got everything hooked up but the spedo wont work so I want to confirm some things.. Does anyone know if the e420 spedo uses a Sine wave or Square wave signal? Also the Pulses Per Mile or frequency that the unit needs? Im also having trouble finding which plug on the back of the spedo is for the signal in, and where the ground is etc.

Hey Slo-Benz, curious if you had any success on getting your speedometer working? I'm planning to use a similar setup, albeit use the abs signal or a crank position sensor pulling off a driveshaft weight
