Save your money on the smart cord.
PARTS:
1. A small inline fuse, 5 amps will be plenty.
2. 2 feet of “two wire phone cord with plug”.
3. Two sets of wire taps. Your choice. Or just tap directly to the wires and solder and tape.
(Most phone cords are two wire.) MOST! two wire GRAY phone cords have a RED and a GREEN wire inside. This is what I used and this is how I will describe the installation.

NOTE 1: My ESCORT 85 X50 would only allow me to wire it one way.
After you strip or use taps on the wires, just touch the plugged in phone wires to the stripped wires and the radar WILL beep or it won't.
Just switch wires if it does not. P.S. Turn on the radar before you try this.

NOTE 2: There are three BLACK wires coming from the light assembly,
two blacks are wired from the lights into a BLUE wire that has shrink wrap on it. This BLUE is the HOT or positive lead. The other BLACK wire coming from the harness is a loose BLACK lead for the entire light assembly (Lights and Motion sensor).

1. Pop off the overhead light case. Use a flat screw driver or just your hands...it is held in by just TWO clips on either side of the light.

2. Unplug the wiring harness to make your life easier.

3. Find the lose BLACK wire and tap that for the ground.
The RED phone wire goes to this.

4. Find the two BLACK wires that are wired to the BLUE light leads
and tap that for the power. The BLUE wire is longer and easier to tap.
The GREEN phone wire goes to this. Use the fuse here between BLUE wire and the GREEN wire.

5. Run the GRAY phone wire with the plug through the open slot in the headliner. The two feet of phone cord will be enough to mount the radar with suction cups anywhere on the high side of the windshield.

6. Plug in the factor harness, TEST EVERYTHING NOW! Reinstall the light case and you are done. P.S. You can leave the RADAR on it will shut down when the light turn off and restart when you turn off the alarm or open the doors.
