We can't get an rpm reading what wire should we tap with the rpm monitor for a dynojet?

 

Buddy,
For the RPM Signal you tap into the violet/green wire on the OBD2 plug, pos. A9.,cheers.

 

is this for 997 turbo also ??

 

We used the same wire on the 997.1TT on a Dynojet as we did on my 996TT. It is on the Harness on the right side of the motor towards the back. There will be 2 harnesses and I want to say it's the top one. The wire is a green with a white stripe (but it maybe the green with the purple, its on the outter part of the harness).

It does work though because we used that wire on my brothers 997.1TT on a Dynojet 248X.

Hope this helps!
