STEP 1 -- CONNECT WIRES
Connect wires below to the matching function of each wire on your receiver (refer to instructions
A.
supplied with receiver). The wire colors of your new receiver may, or may not, match the wire
colors of the adaptor. Match adaptor and receiver wires by function, disregarding color.
If your receiver does not have a Dimmer or Illumination wire, tape off the Orange/White or Orange wire of this adaptor (the one not used).
B.
C.
If there is no Ground wire in the factory harness, connect new receiver’s Ground wire to vehicle chassis.
Individually tape off any unused wires.

STEP 1 -- CONNECT WIRES (continued)
F.
The speaker plug in this harness set may not be directly
compatible with your vehicle’s wiring if the vehicle is equipped
with a JBL, or Premium Sound amplifier. An additional adaptor
may be needed to correctly interface an aftermarket receiver
with a JBL or Premium Sound amplifier.
In some cases, Ford’s front speaker negative leads (wires) are
G.
reversed. To test, plug in the wiring harness. Touch the
positive and negative leads of the left speaker to a “C” or “D”
cell battery (1 1/2 volts). If you hear a “pop”, your vehicle is
wired normally. If no “pop” is heard, connect the front speaker
negative leads in reverse. Left front speaker negative
becomes right front speaker negative.
H.
Individually tape off any unused wires.
I.
Make final connections following instructions on page 3.
