Try the CKP wire, youll have to play with the ECU tho, the harness is a biotch to put back on if your new

 

yeah, the ecu is a b*tch to work on: big wire loom, trying to splice some wire is a nightmare, and it's far up. I had a choice for getting that tach signal: ignition coils, ecu, or (from what I read) from the gauge cluster. The gauge cluster was by far the best choice, for me!

Anyway, I finally got the tach signal to read properly. The problem was that I had to get my alarm brain to learn the tach: turn the car on, let it idle, press the valet button (it will chirp), and that's it. But the valet button would never chirp. The problem was that I had to connect my door trigger/dome light. Because I didn't have another relay, I simulated the door opening by connecting the proper alarm wire to my brake switch. So by holding the brake pedal, it acted as opening the door. And that was it, now my RS almost works (lol). When the car turns on via RS, it only idles for about 5 seconds and then dies. I'm looking into that one now :-)
