Locate the factory wiring harness in the 
dash. Metra recommends using the 
proper mating adaptor and making 
connections as shown. (Isolate and 
individually tape off the ends of any 
unused wires to prevent electrical short 
circuit).
Re-connect the battery terminal and test the unit 
for proper operation. Mount the head unit/kit 
assembly to the sub-dash with those screws 
previously removed in step #1. (It may be 
necessary to trim the ends of the Mounting Tabs 
to provide proper clearance).

2-SHAFT HEAD UNITS: Snap the Faceplate onto the front of the Radio Housing. (For 
applications using Faceplate #2, cut and remove the bottom portion of the Faceplate). Slide 
the aftermarket head unit into the kit and secure with shaft nuts.  (see Fig. A)
DIN HEAD UNITS: Cut and remove the shaft supports from the Faceplate and Radio 
Housing. (For applications using Faceplate #2, cut and remove the bottom portion of the 
Faceplate). Snap the Faceplate onto the front of the Housing. Slide the DIN cage into the kit 
and secure by bending the metal locking tabs down. Slide the aftermarket head unit into the 
cage until secure.  (see Fig. B)
(If an equalizer will be included, slide the unit into the back of the Radio Housing and secure. 
If an equalizer will NOT be included, snap the Equalizer Dummy Plate into the opening).
