Installing a Mirror Monitor in a 2014 dual cab

Hi BooBoo,

The only effective way is to obtain a 12v extension cord (about 5 metres) and run it under the edge of the hood lining, down the left hand side of the door pillar (the cover should just unclip when you pull it) then under the dash, etc. to where your connection point is.

If you are just looking at a 12v power feed, you shouldn't need to connect it the a 12v socket. you could connect it to the fuse block with an "add a circuit" double fuse connector which piggybacks onto an existing circuit. The negative wire can be connected to the vehicle earth anywhere along the route.

My mirror monitor only required the one connection to the mirror, (by the same route as I have described). The power cable and reverse switch sensor wire terminated at a junction box I positioned behind the side foot well panel.

I have tried several rearview screens and the one on the mirror was the worst of all especially if you wear glasses.

Wearing bifocals I couldnt focus enough in time to have a brief glance at it and so ended up with a screen on the dash which was fine.
Unless the screens have improved a lot I found that the picture couldnt overcome the mirror function and never appeared clearly. Even tried a matte screen protector. Was glad to be rid of it.
Have wired several dash cams up as stated but be careful which fuse you tap into Definitely NOT AIRBAG ones. Also make sure the screen actually runs on 12 v and hasnt got a stepdown in the ciggy plug ( if it has one)
I use a addafuse and connect a ciggy socket to it as the dashcams are usually 5 V Saves cutting the wires and allows you to remove later if required.

Thanks gentlemen
I will get an addafuse tomorrow and have a go.
