Engine RPM signal

...okay perhaps there no other way other than to get to the tach signal wire.....is there a good source of information that will confirm which one it is in the cluster harnesses?

PIN number, wire colour, and harness kinda thing.........for 2000.

Wiring diagrams here I come.

There is a wire on the ODBII plug that is connected to tach signal. I'll look tomorrow to see which one. I had a wire connected to my Traqmate Datalogger at one time.

Yes that is true.....pretty sure I have seen OBD II shift lights.

I think that this would be the cleanest solution provided provided the proper wire tap hardware is used.....and the OBD wire isn’t screwed up.

Thanks.....Bentley EWDs were not helpful. Then again I am not an Electrical wizard either

Pin#9 on the OBD port. Violet/Green Wire, on my car which is a 2003.

Thank you sir.....I will try and verify if the wire colours are the same for a 2000.

My guess is that CAN bus arrangements will have changed it
