Hi
I have had some great advice on the forum explaing the difference with ECM an PCM, I need to know however which wire and Pin number to connect my tach wire from my remote start its a Audiovox remote start, My problem is if I program the remote for voltage sense the car will start and stop,restart and everything is OK off I go,however if I put it in Tach sense the car will just start stop and restart stop, I have tried hooking onto a injector wire,not the common color,when I say common color I mean the passenger side has 3 blue and the driver has 3 black,each injector has 3 wires,using a votage meter I connected to the one that had a reading that varied from 1 -3 volts, then I program the remote for tach mode,nothing still the same,then I have heard I should connect to the ECM,but do not know which wire is the tach wire in the ECM,I live in Norway and introducing a remote start to the dealer was like showing fire to a caveman,any help would be appreciated. Oh by the way I have a 300 CRD
Thanks
