What wire colors does the Type C reverse polarity keyless module use?

RED (+12V constant), BLACK (ground), BLUE/BLACK and BROWN/BLACK (unlock), PURPLE and PURPLE/BLACK (fused to +12V constant), GREEN/BLACK and WHITE/BLACK (lock).

Where does the purple/black wire connect?

The PURPLE WITH BLACK STRIPE wire connects through a fuse to +12V constant power, per the note on the diagram.

Do I need to cut the factory wiring for this installation?

Yes. The diagram shows "CUT HERE" points on the wires to the power door lock motor, and a note states you will need to cut factory wiring to make an end-to-end connection (see "Making Connections" on page 3).

How should the antenna be installed?

Keep the yellow antenna as straight as possible and tape the end to hold it straight.

Which keyless module wires handle lock and unlock?

BLUE/BLACK and BROWN/BLACK are the unlock wires; GREEN/BLACK and WHITE/BLACK are the lock wires.

This document is one page of an installation instruction sheet for an aftermarket keyless entry system, showing the "Type C" Reverse Polarity wiring configuration for connecting a keyless module to a vehicle's power door lock motor. The diagram identifies each wire from the keyless module by color and function: RED to +12V constant, BLACK to ground, BLUE/BLACK and BROWN/BLACK for unlock, PURPLE and PURPLE/BLACK (fused, to +12V constant), and GREEN/BLACK and WHITE/BLACK for lock. "CUT HERE" markers indicate where the factory wiring between the lock/unlock switches and the power door lock motor must be severed to splice in the module for end-to-end connections. Notes instruct the installer to connect the purple-with-black-stripe wire from the fuse to +12V constant power, to keep the yellow antenna as straight as possible (taping the end to hold it straight), and to refer to "Making Connections" on page 3 for cutting factory wiring. A reader can learn the complete wire color code and splice points needed to install this reverse-polarity (Type C) keyless entry system on a vehicle with reverse-polarity power door locks. No specific vehicle year, make, model, fuse amperage, or part numbers are stated on this page.
