3. Install the gateway module bracket (380121) on the “floor” of the junction box.
-

Bracket should be positioned as far rearward as possible (temporary install the module
on the bracket – module should almost touch the back panel).

NOTE
Vehicles may already have two pre-drilled holes for bracket installation
– Make sure holes are positioned properly (far back) to clear vehicle harness and
plastic protective panel before securing bracket/module.

If no holes are factory drilled or if holes are not positioned properly, mark the bracket
lower tab and screw hole positions with a sharpie and drill the two screw holes using an
angle drill and a 9/64” (3mm) drill bit.

-

Secure the bracket to the junction box floor using two of the supplied #10 screws
(502868).
