Hey everyone. I've ordered some LEDs to install in my car. Quite excited to install them! I want them to power when I open my door (function the same as my dome light) and I also want to have a switch with which I can power them. For now, I can just not worry about the switch though, I just need help with the wiring. My car, (2010 Corolla) has a dome light, with two wires we need to worry about. We have a pink wire which is always live. Then, we have the gray wire, which is the switch on the circuit. It is live, until the door is open, where it is grounded. So its a negative switch. I want to hook these up to my dimmer in my dashboard which is a positive circuit. So, I am going to use a relay. Would the correct configuration be: [COLOR=#000000][FONT=verdana](Confused a smidge about the order of 85 and 86 as a result of the negative switch, so is this right or do I have to flip or ground one?)(Or does the gray wire go on 85 and a different 12v on 86?)[/FONT][/COLOR] [COLOR=#000000][FONT=verdana]85-pink wire[/FONT][/COLOR] [COLOR=#000000][FONT=verdana]86-gray wire[/FONT][/COLOR] [COLOR=#000000][FONT=verdana]87a- Dimmer[/FONT][/COLOR] [COLOR=#000000][FONT=verdana]87- (could this just be any positive 12v source? or should it be related to the dome)[/FONT][/COLOR] [COLOR=#000000][FONT=verdana]30- LEDs Advice?

I recently moved into my home (built in 1975) and did a lot of painting. At the same time, I removed all the old outlets and installed new tamper resistant equivalents. But, I forgot to make note of which outlet had the tab broken off for the switch! Now I have a dead switch in the room. I went up to the attic and checked out how it is wired. The switch box by the entry door has two switches. One switch goes to the closet light and one switch goes to the closest outlet (outlet 1) that is also bridged to the outlet opposite the entry door (outlet 2). It seems complicated to visualize so I made a diagram... [ATTACH]3540[/ATTACH] Red box = outlets Orange box = switch box Light blue and dark blue = wiring (from attic) Since the line from the switch connects these two outlets, I figured one of these two HAS to be the switch controlled outlet. The other 3 outlets' wiring goes down-ward into the floor, so I think they are not connected to the switch. Round one: I installed a new outlet with the tab removed at outlet #1 and a new outlet with the tab intact at outlet #2. Switch did not work. Round two: I installed a new outlet with the tab intact at outlet #1 and a new outlet with the tab removed at outlet #2. Switch still does not work. :confused: Does this mean that one of the other three outlets is controlled by the switch even though their wiring from the attic doesn't connect to the switch box? I have not checked any of the tabs on those outlets yet. There is also a light installed in the middle of the room on the ceiling, but it is wired to the attic light and not controlled by any of the switches. So, that can be ruled out as a source of the problem.
