Default 958 Cayenne DIY: Radar Detector Wire Harness Install at Upper Console

When tapping switched power from your upper console’s auto dimming mirror lines for your favorite radar detector , you have two choices:

1. Follow these instructions for a splice free connection
2. Cut and splice into the lines (not my choice and I won’t present it as a solution)

Disclaimer. If you are not comfortable with electrical and auto trim work, you have two choices:

1. Next time it is in for service at your preferred shop and ask them to do it for you.
2. Leave the Mirrortap, $20 and a short note for you tech on the front seat because they have done a few of these and they can do this in about 15 minutes.

You will need:

- Patience removing the upper console
- 958 2011 Porsche Cayenne S with auto-dimming rear view mirror. This may certainly be applicable to other Cayennes.
- Valentine 1 radar detector
- A warm day or heated garage (plastic can break easier when cold)
- Voltmeter with thin probes
- Non-marring panel removers
- Electrical tape
- MirrorTap MT-2012. 12” long lead with built in fuse. www.mirrortap.com
- 2 small zip ties
- Protective covers for the interior
- Clean hands when handling interior parts around the fabric headliner

Cover everything that you do not want damaged: dash, center console, steering wheel, passenger seat, driver seat.

Remove key from ignition. Do not leave it in…remove it!

I did not disconnect the battery. Why? Because I removed the key from the ignition.

1. Remove the cover between the upper console and the cover to the mirror base. It is help in place by friction fittings.
2. Remove the console.
a. The metal spring clip ends can get hooked behind the headliner.
b. Start with releasing the rear first and then move forward.
3. Find the yellow auto-dimming mirror wire connections.
4. Test the brown and blue leads if desired with your voltmeter.
5. Slip the black lead into the brown wire’s connector back (ground) and the red leas into the blue wire’s connector back (switch positive power).
6. Wrap the slightly exposed lead ends and yellow connector end with electrical tape.
7. Zip tie the MirrorTap leads to the auto-dimming harness to keep in place.
8. Route your MirrorTap leads out to your desired locations.
9. Mount the radar detector.
10. Reconnect all upper console electrical connections.
11. Insert ignition key and power up the electrical. Test your radar detector.
12. Put everything back together in reverse order.
