Right... Having been through a bitch of a house move (and still ongoing) over the last year I'm slowly getting back to doing some work on the car. As such I can't remember half of what I did the last time I was in the garage.

On the R1 ECU there is a yellow/blue out and a yellow/black out. One is the tacho output and one is the speedo output. Which one is which.

I know I had the answer to this written down somewhere (maybe even from on here) but I can't for the life of me find it and I was informed that I should be able to use these as the inputs for my gauges so I might aswell try the existing wiring first.

Cheers
Andy

Wiring for my acumen GI has the tacho as yellow/black

Cheers, that'll do nicely
