hey guys

I was going over the install of my avistart 3200 that was completed a few weeeks back. I noticed the installer did not use a tach sense in the engine compartment. The only wires that come thru the firewall are the power, ground, and the hood pinswitch. Is it possible it was connected somewhere in the passenger compartment?

I have an 01 ram 1500 automatic

thanks, tim

It is possible to connect the tach wire somewhere under the dash. Some vehicles make it easy to get to the wire in the driver/ passenger side. The only true way you can find out is to ask the installer, or test all the wires from the brain of the alarm.

My Personal Installer Note: Connectors are easy, neat, and professional. But do you know how to crimp properly?

Notes:
Note : Diesel glow plug wire is a ORANGE / black(-) "see direct fax document #1090", and the tach wire is a gray/black. Both wires are located on the center of the firewall. There are two black plugs, the wires are in the plug without the white insert.
*1 Keyless models use positive trigger for lock, and 5-wire for unlock. Can also find wires at the central timer module to the right side of the steering column, lock is ORANGE / green, unlock is pink/green.
*2 To avoid dome delay, use tan for the drivers door and BLACK/ lt. blue for the passenger door.  Both wires are located at the central timer module to the right side of the steering column.  Use both wires and diode isolate each.
*3 Factory disarm is a negative trigger through a 1.5K (1500) ohm resistor.
*4  Diesel tach wire is gray/black at the ECM on the passenger side firewall in connector C-1, pin 8
*5 This wire requires a high current negative, must use relay.
