12. Coat the O-ring(s) on the detector(s) with silicon grease, then
snap the connector onto the mounted detector and secure
cable to detector bracket using appropriate cable clamp and
1/4-20 x 1/2 in. socket head screw supplied in detector cable
clamp package shipping assembly.

13. Complete this process on each detector in the system.
14. Attach the ground wire to the vehicle ground. Do this by
mounting a sealed junction box in a convenient, protected
location. The box must be mounted to a rigid support. Run the
detection circuit cable to the box and attach to grounding
screw. See Figure 30.
15. Attach the end-of-line resistor assembly, Part No. 426520.
See Figure 30. See instruction sheet included with end-of-line
resistor shipping assembly for detailed assembly information.
16. Run cable to the terminal strip at the control module. Make
certain cable is not subject to damage. Install cable to termi-
nals 3 and 4.
