THE 14-PIN MAIN HARNESS
H1
This wire is the main (–) ground input to the 1370
system. Be sure to connect this wire securely
to a good ground source. Most security system
installation problems result from a bad ground
connection! (The BLK wire splits into two wires
to act as the ground source of the H2 sensor har­
ness. See page 5.)
H1-10 BLK wire: (–) System Ground
This wire is one of four wires from the H1 main harness that forms the

5 siren chirps. (See page 12 in the Owner’s Guide for more information.)

The 1370S does not support door locking on vehicles that
use vacuum pump door locks (most Mercedes) or vehicles that require 2
pulses for unlock. See “Type­E” on page 11.
