I need to know which wire to splice into if there is one that is under the steering wheel near the fuse box, cuz i don't want to splice the blue wire in the distributer, the blue wire behind the tach, or the wire in the Ecu just in case it shorts, i don't want that being blown, so is there any other wire i can tap into? (BTW i am runnning a PR3 OBD0 B16 for added info., might help) HELP ME!!!!!!!

 

why not tap into the ecu??? its already tapped for vtec right.

 

well we re-pined everything, any other ideas

 

bump, this is all i need to be donw with, which wire to tap for RPM?
