Hi all, after reading Diablo243's Zenesis alarm/remote start DIY I figured that instead of paying out the rear to have someone install the Audiovox APS997a for me, I had sufficient knowledge of car wiring to try it myself. However, I have come across two problems that I am having, and I'm not sure if it's just the wrong wires I'm using or what, hopefully someone can help.

First, The Audiovox instructions list the tach wire for my alarm as the "Tachometer Input Wire" and states that the "wire will be routed to the vehicle ECM tach input or run to the engine compartment and connect to the negative side of the ignition coil." I connected the wire to the black wire at pin 9 going to the ODBII connector and tried the tach learning program for my alarm multiple times, and it still registers as not reading a tach signal. Since the wire for the xb that is in Diablo's instructions is listed as tach output, and my alarm needs tach input, would this be the incorrect wire?

Secondly, I am having trouble with the door lock/unlock. I connected the negative door trigger wire to the red/white (-), and connected the (-) lock and unlock wires to the correct wires in Diablo's DIY to match what is needed for my alarm. However, the alarm will not unlock the doors when they are locked, and the lock sequence locks all the doors, but then automatically unlocks the driver's door again, and will not lock it. Any thoughts on this one, I'm not sure where to begin with it.

Thanks for any input!!
