Lighted Door Sills Installation Instructions for MUSTANG 1994-2004

Step 1 Using an 8mm wrench, loosen the negative battery terminal and remove from battery.

Figure A.
 
Step 2 Remove both (left and right) inner factory sill plates by grasping and pulling straight up and evenly both sides.

Figure B.
 
Step 3 Remove both driver's side and passenger side kick panels by prying retaining pin out, then pulling bottom out towards the rear of the car as shown in Figures C and D.

Figure C

Figure D
 
Step 4 Using a hack saw, cut two small slits about 1/8th inch deep 1/8 inch apart where shown in Figures J (passenger side) and L (driver's side) at rocker panel seem. Then break off center portion to allow for shielded wires to pass through to inside passenger compartment. File the sharp inside edges of U-shaped channels on both sides of vehicle to prevent wire chafing.

Step 5 Remove the adhesive backing on one of the voltage converters and apply to vehicle on driver's side where shown in

Figure F.
 
Step 6 Now do the same with the other converter and apply to exact opposite side of car in the lower kick panel area.

Step 7

For 1999 through 2004 Mustangs:


Step 7a  Pull back the carpet by the driver's side sill area to access the wiring harness along side of the driver's seat. Connect the short end of the fused positive (+) wire to the lime green wire with orange stripe in the factory wiring harness as shown in Figure I.

Figure I

Step 7b Connect the other end of fused positive wire to red (+) wire of driver's side voltage converter. At that same connection, connect one end of the red side of long red/black wire. (supplied)

Step 7c In the upper driver's side kick panel, locate the grey with red stripe wire in the 20 pin connector of the body control module and connect the black (-) side of long red/black wire with diode to this wire.

Step 7d Now that both red and black wires are connected at one end, run the other end under the carpet along firewall behind center console to the passenger side voltage converter.
Step 7e Connect the other end of the red/black wires to the red and black wires of the passenger side voltage converter.

Step 7f  In that same 20 pin connector as described in step 7c, find the yellow and black wire and connect the black (-) side of the driver's side voltage converter with diode to this wire.

 

For 1996 through 1998 Mustangs:

Step 7a Connect the black wires of both voltage converters to the blue and orange wires located in both driver's and passenger side kick panel area.
Step 7b Connect the short end of the positive (+) fused wire to the yellow constant 12v positive (+) wire located in the ignition wiring harness next to steering column under the dash.

 

For 1994 and 1995 Mustangs:


Step 7a Connect the short end of the fused (+) wire to the black and light blue wire found in the lower driver's side kick panel area.

Step 7b Connect the longer end of the fused (+) wire to the red (+) wire of the driver's side voltage converter. At that same connection, connect one end of the red side of long black/red wire.

Step 7c Run the other end under the carpet along firewall behind center console to the passenger side voltage converter.


Step 7d  Connect the other end of the red/black wires to the red and black wires of the passenger side voltage converter.

Step 7e Connect the last black wire of the long red/black wire to the driver's side voltage converter black wire, then to negative ground.
 
Step 8 Prepare factory sill plates by thorough cleaning with warm soap and water, drying and cleaning again with rubbing alcohol and clean terry cloth towel. Be sure that no residue from waxes or cleaners are present on the top surface as this will impair the adhesion of sill plate cover.
 
Step 9 Remove the adhesive backing from the sill plate covers and apply over lower sill plates being sure that the black sill plate wires exit to back side through the cut u-shaped groove. Apply firm pressure around the outer portion of sill plate cover to promote good adhesion.
 
Step 10 Wrap wire with the protective wrap where wire travels through groove to prevent wire chafing as shown in Figures P and N and connect wire from lighted sills to the connector of the voltage converter pushing firmly until connector locks in place.

Figure N
 
Step11 Reinstall kick panels in reverse order as removed and fasten with retaining pin.
 
Step 12 Snap upper factory sill plates in place being sure that wires are routed through the u-shaped groove and are tucked under carpet.
 
Step13 Reconnect negative battery terminal and tighten.
