i have a 03 24v i need to locate the tach wirew to installe remote start . i got back the truck after the alarm was installed they said that they need at least 2 wk to figure this out if there is no tach wire i will just put a signal gen off of the alt thanks james <br>

 

I believe the engine speed is picked up from the CPS which is located by the starter. The starter has to come off to get to the sensor.
