Green w/Orange Trace Wire: Tachometer Input Signal
This wire will continually monitor the engine tach rate while the unit is under power of the Remote Start
module. This wire will be routed to the vehicle ECM tach input or through the firewall into the engine
compartment and connect to the negative side of the ignition coil. This Remote Start unit learns the tach
rate of the vehicle and in most cases will operate properly from a single coil, single injector, or one multi
coil pack regardless of the number of cylinders. In certain vehicle with a single coil for each cylinder, it
may be necessary to connect this wire to more than one cylinder for proper tach reference. See multi
coil wiring detail shown later in this manual for additional information. (See feature # 10 for OVERCRANK
information)

If the vehicle's door courtesy light switches ground when the door is opened, (Most GMs and Imports),
you must connect this wire to the negative output from one of the vehicle's door pin switches. In most
cases the Brown wire will need to be connected to only one door switch no matter how many doors the
vehicle has as most door lighting circuits are wired in parallel. This wire will be shunted when remote
