1999 Olds Silhouette

Need some info for this vehicle for remote start. Not sure where the tach wire is. The data base says a white wire in some plug on the left side of engine. Anyone have more specifics or another location and the E.C.M. location. Thanks.

Notes:
NOTE: This vehicle is equipped with the pass-key III immobilizer. Use DEI part number 555G or 555U to bypass during remote start mode. Use the lt. green (-) key sense wire at the steering column to interrupt the blue wire on the 555U so that when the key is inserted to do take over the vehicle does not see two transponders at the same time. Refer to directfax document #1079 for wiring information. *1 To avoid the domelight delay use tan for the drivers door, blue for the passenger door and the liftgate, and orange for the sliding doors. All wires are negative trigger, located at the BCM and all need to be diode isolated from eachother.    *2 This wire is only activated when the wipers are in the high/fast position. There is not a wire for the low setting. *3 The door lock wires will only meter when turning the key in either door key cylinder. Also have to program the door lock pulse duration for 3.5 seconds to unlock the doors. On vehicles without the factory alarm, use lt. blue for lock and white for unlock. Find the wires in either kick panel. *4 To disarm the factory alarm without unlocking the doors, use a 0.8 second pulse on the unlock wire. *5 The ignition coil pack is on the top of the engine on the passenger side. The PCM is in the air cleaner assembly on the front of the engine compartment on the driver side, the wire is in the blue plug in pin 8. *6 This wire is for the passenger side power sliding door.
