Step 2: Installation

Connections:

•  If you have an aftermarket radio, check your owner’s manual for wiring 
information. You will need to cut off the white rectangular connector on 
the Harness. 

•  Wiring code is: Red /Right + Black /Right- Green /Left+ Gray /Left-.

•  For factory radios, connect the white rectangular connector to back of 
the radio. Gently push in until a “click” sound is heard.

•  Run the harness the length of the center console.

•  Route the Harness the length of the center console to approximately 
1 foot from the rear of the console. Separate the harness so that one 
half goes down through the holes in the carpet used for the console 
mounting screws and out the bottom where the seat belt anchor bolts 
are attached. (HINT: Use a coat hanger to guide the wires) It may be 
helpful to remove the six plastic pop clips holding down the carpet to the 
rear panel to help gain access to the carpet. 

Speaker Installation:

•  1994-97

½

: Locate factory headrest connector under the front of the 

seat near the center of the Miata.

•  Plug Clearwater Harness into factory connector.

•  Refer to the rest of the Installation.

•  1990-97

½

: Slide each seat forward. Unzip the top of each headrest 

cover. Fold forward the cover and remove the perforated white plastic 
cover. Fold the top of the seat cover back (as you would fold back the 
“hood” of a coat) to expose the foam of the seat.

•  Straighten a coat hanger and form a small loop about 3/4” long, 
apply tape to the tip to cover any sharp edges. Slide the coat hanger 
down from the back of the seat cover from top to the bottom. Attach the 
speaker wires to the hanger with tape and gently pull the hanger/wire 
assembly up the back of each seat.

•  Locate the small round hole in the middle of the back of each seat. 
The headrest wires will need to go through the foam towards the upper 
front of each seat. Feed the coat hanger (with the wires attached with 
tape) through the hole in the seat .Your seat may have a pre-punched 
hole going through the seat. This hole goes upward from the back 
of the seat up and forward towards the front of the seat. If not, use a 
coat hanger or a long screwdriver to route the wires through the seat. 
(HINT: It may be helpful to remove the center circular metal staple that 
holds the front seat cover below the headrest speaker cavities. This will
