Mirrortap 2012 rearview mirror/camera wiring

Hello everyone! I have a quick question about some wiring. I am in process of mounting my Escort Redline to my mirror with a product called "Blendmount." This has worked great but I am also trying to hardwire the detector to the rearview mirrors power source with a wiring kit I got from Mirrortap. I have have a 2012 access TRD with the rearview camera display built into the rearview mirror. Has anyone used the Mirrortap wiring kit in a 2012 Taco? I am having trouble determing the wiring configuration on the molex plug at the top of rearview mirrors wiring harness, just below where the headliner meets the front windshield. I have a multimeter, but I cant seem to get the prongs into the molex plug to determine each wires status. I am looking for the 12v power and ground wires. Any suggestions? As always thank you ahead of time for your comments!

 

Use a sewing needle, or a stick/push pin. Inset into connector and touch your meter to the needle/pin.

 

Thanks for the tip, should have thought about that earlier! As far as the "wiretap" installation, after messing with it for a few hours yesterday I finally completed the installation! (After much trial an error)

IF anyone else is interested in knowing the procedure for installation I will try to explain it briefly. First off this explanation is for my 2012 Access cab TRD Taco with the backup camera screen built into the rear view mirror. I cant speak for any other models especially when it comes to the wiring. Their may be an easier way to do it, but after trying multiple different methods this is the only way I could install the mirrortap cord along with the Blendmount radar detector mirror mount. I have an Escort Redline which is now incorporated into my setup. **Test your wiring with a multimeter** I am sharing these tips based on the my experience and setup of MY Taco. I don't work for Mirrortap, Blendmount, or Toyota. I am not a mechanic nor an electrician, just a guy with a truck, a radar detector, and a real dislike of wires dangling everywhere. So use this advice at your own discretion.

1. The first thing I would do is remove the entire rear view mirror from the windshield. This involves first removing the plastic wire cover that runs into the upwards from the stem of the rear view mirror up and slightly under the headliner. This exposes the top side of the molex wiring connector which you will eventually tap in to.

2. Disconnect above mentioned molex connector/coupler. Now there will be a series of bundled wires protruding/dangling from the point where the headliner meets the windshield.

3. Pull upwards to slide/remove the black plastic wire cover that still attached to the rearview mirror. This is the decorative plastic piece that is covering the rear view mirrors lower molex connector/coupler. (the remaining connector piece you just disconnected from the above mentioned step)

4. Unscrew and remove the entire rear view mirror unit from the windshield. There should be a single screw that keeps the mirror tight with the windshield mount
5. With the mirror completely removed from the windshield, slide the molex connector off the mount that is attached to the rear view mirror unit.

This is where it took some trial and error for me.

6. Take the positive wire(red)m and insert into the back(windshield facing side of the molex connector attached to the rearview mirror) The positive 12v power spot is the light green wire which if looking at the molex connector attached to the mirror from the windshield facing towards the rear of the truck perspective, would be the bottom right hole with a wire coming out of it.

7. insert the black(ground) lead into the hole directly adjacent and to the left one slot of the positive lead you previously inserted.
Inserting these prongs into their respective slots was not easy. It took me multiple attempts to find the correct side of the rectangular slot to find enough space for the prong to fit correctly. Once you have both leads securely in their respective slots you are pretty much done

8.At this point I would test your setup before reassembling the mirror unit. Plug your detector in and fire up the ignition. If you have power, you should be good to go. Just reassemble (carefully) in reverse order.

 

bluebird1717,
I have a 2010 double cab, the wiring on the molex connector looks same as yours, with only 5 wires coming in on each row. I have seen pics with 7 wires on each row. Mine has 2 empty slots on each row. I'm' trying to connect the mirror-tap without taking off the mirror. My question is how did you connect the ground (black) wire into the empty hole? to me it seems to keep going in without getting snug. I also have to figure out to connect the red one.

 

Came across this thread through a search. Question on item #7: what tool did you use (if any) to ensure that the prongs didn't snap off when trying to insert them into their respective slots? Seems like a tight fit based on the pictures. I'm considering this on a 2012, but want to be sure that it's a durable, long lasting mod. How is yours holding up today?

 

Thank you very much for publishing this thread helped me out figuring the wiring.

Not going to say pushing pins in was an easy task, but after using some sand paper it worked out fine. Not a lot of room there for sure.
