Wiring up Aftermarket Tacho - RB20

[RB20VLCT]

Hi,

I have an Auto Guage Tacho that i want to wire up to my VL Calais (RB20). Obviously i know where the negative and positive wires go, but where do i connect the wire where it gets its signal from? Does it run straight off the ecu? Anyone know which wire? Thanks guys...

Hey, I had to check up on the HKS USA website to find which wire to connect my Monster Tacho to off the ECU, They had a very extensive list of cars.
I think Mayhem or Butters put me onto it, maybe give them a PM.

if you cant get a reading from teh ecu you could always use teh CAS

the taco runs straight off the coils there should be a spare wire running off one of your coils thats the goer
