View the thread, titled "12v Switch Wiring DIY question" which is posted in DIY Electrical Advice on Electricians Forums.

So, I am a relative beginner (only fiddle when needed and usually following clear instructions or diagrams) when it comes to 12v switches and relays, but I am needing some help with a set of switches and a micro relay I purchased from Amazon (those who purchase here know most stuff comes with either no instructions or very basic and unclear sets). The switches are 5 pin latching on/off with an led halo light and come prewired with three wires and, as stated, the relays are micro 4-pin 12v 30A SPST labeled with pins 1,2,3 and 5. I am assuming that the relay, though numbered different, is essentially the same and that pin 1 = 86 (+), Pin 2 = 85 (-), Pin 3 = 30 (+), and Pin 5 = 87 (+ to device when closed).

Now for the specifics:

Yellow wire of the switch is soldered to Common (which I assume would go directly to positive of the device.

Red wire of the switch is soldered to both NC & "+" (kind of bent and bridged, so I assume this means that the halo would illuminate when the button is pushed and in the ON position). For the one I want to be able to control accessories allowed to operate despite key position, this wire would go to battery positive, essentially giving it power at any time it is in the latched ON position (yes, I understand this would allow a vampiric draw if I failed to switch it off) and for the ones that are only powered when the key is on, this would be wired to the relay's pin 5 [87] while the relays pin 3 [30] would be wired to battery positive and relay pin 1 [86] to the keyed ACC.

Black wire of the switch is soldered to "-" which I assume is basically wired to ground for the sake of the led being able to illuminate.

Here comes the kicker part, and my absolute confusion: One of the items I want to leave to be able to operate at any time is a set of bluetooth LEDs that come prewired with a switch in the ground wire. This switch is actually very inconvenient as it would be under the seat since that is where the controller is placed. I am assuming I would need rewire the one LED switch so that the NC and + are separated and that the Common and NC would complete a ground circuit when the button is pushed and in the ON position. I could bridge Common and "-" of the switch and run the Yellow wire to the switches NC pin and the other end to the ground of the controller. Red switch wire would essentially just be powering the LED of the switch.

Are my assumptions correct, or am I making a total A$$ of myself (lol)? If I am not correct, would you mind giving me a better understanding?
