Re: Hardwire Radar Detector Install (F10)

Was finally able to do it. Did not use blue T tap this time. Just used traditional wire to wire. The ground is tough, just to get to that bolt. Its at a very tight spot.

Can somebody clarify as to why is it better to tap into mirror or sunroof power as opposed to use 8 feet dongy( hidden behind headliner/pillar )connected to power outlet under glove compartment?

I like the clean installation the mirror power has and also I use the under dash acc. plug for Zumo GPS ( I have factory navi, that piece o'sh@t :-))

The 8 foot wire option is best if you are wary of going into the mirror which is not that difficult. If you don't need the under dash acc plug that is easy to install so your best bet.
Best regards,
Don M

It isn't broken yet but I can fix that!

Started to do the install this way with a t-tap/vampire clip, however, I realized how evil vampire clips can be.

I know it isn't very likely, however, vampire clips can split the wire in half over time which wouldn't be fun to repair. Folks recommend soldering and heat shrinking.

The method I settled on was routing the wires down through the a pillar (along with the other sunroof and rearview mirror wires) into the fuse box. I used a bussman add-a-fuse and grounded to the chasis right by the fuse box.

I wont have to worry about wires splitting due to a vampire/t tap now and I have the added protection of an additional fuse.

I think this is the cleanest install possible as it doesn't involve splicing any wires or removing any amount of insulation from the wires. Additionally you don't have to worry about getting access to that bolt for a ground.

Smile Thanks! Worked!!

I went through the steps today to install the Escort detector in my 2014 535ix M-Sport. Everything went great, thanks for the information on getting that center console out. It would have been more trouble if I hadn't had your posting to go by.
I've also done this to my previous 2008 and 2010 535's but soldered the detector in vs. using the splices. My only comment on the splices is to make sure they are clamped tightly. Detector now comes on when the car is started and turns off when the delay is up.
Good info, Thanks!
