Blue wire: Pin 17 on the large 18 pin connector behind the
radio. If there is already a wire in this slot, then simply tap into
it. If this slot is empty, use the wire that we’ve provided for you
on the 18 pin dummy plug. See Illustration C. *Note: We will
provide you with a small 18-pin “dummy” connector which is
used as a place holder. Simply remove each wire, one at a time
and re-insert them into the same pin-position on the existing
18-pin connector behind the radio.
Audio leads are in the small place holding dummy plug.
White wire: Cut wire located at Pin 2 of Factory 8-pin Power-
Plug (usually yellow/white stripe). Connect White wire directly
to pin 2. Note: Pin 2 is the wire closest to the release lever of
the plug. After programming is done, reconnect the factory
wire.
Remember- not the 18 pin connector, but the power plug.
Small square connector: Plug directly behind the radio. This
new plug will be replacing an existing identical plug. Simply
remove the only 2 wires on the original plug and re-insert them
into the same pin-position on your new connector.
