tach sense wire 01 ram

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.
