so I added a relay at the BCM behind the glove box to turn on three of my accessories (dash cam, radar detector, and my ambient lighting system), to trigger this relay, I used the cars ACC sense wire that shows 12v any time the car is turned on (running or not) and shuts off as soon you you press the start/stop button. and yes, regardless of what the current draw is on the device that you are installing, I always recommend using a relay as the cars ACC wire is very thing and low current and I wouldn't want to over draw it.the switched ignition power tap is proving difficult
Thanks for the info, I used an "add-a-fuse" that looks identical to the one you linked to. I tried to use the cigarette lighter fuse but the plastic wouldn't clear the fuse housing plastic.I bought a rearview mirror with Homelink controls so I can control my garage door, it needed constant and switched.
Also bought a Garmin Dash Cam 55, and out of the box only needs switched, but I got the "parking camera" kit and that also needed constant power.
I ended up using two of these: http://a.co/fBI8pIH and as for locations tapped:
- F66 : Driver Door Lock -> Constant power
- F87 : Heated Steering Wheel -> Switched
the switched lead does seem to power on when the car is "woken up" but it's a good enough source of power that I'm happy with how it works.
I refuse to use those, usually when they are used, as they are inserted, they tend to cut through some of the wire being tapped into. sometime they cut through MOST of the wire being tapped into.My Valentine RD has a vampire clip intended to be attached to the wiring in the overhead light/sunroof module. Has anyone tried this?
