| Rear Window Defroster |
The rear window defroster timer is
integrated into the switch assembly. To engage the timer from a momentary
output of an alarm, disassemble the switch and solder two wires to the
circuit board where the push button contacts connect. Then use an additional
relay to emulate the button being depressed. |

To bypass the factory timer module
all together and supply +12V directly to the defroster elements, use
a latching output of the remote start module to drive a relay that connects
the Yellow wire (constant +12V) with the Gray/Yellow wire on the defrost
switch. |
