Relay wiring help?

[dodge68charger]

Hey Guys,

Looking to wire up some accessories in my 68 charger. Led lights, fans, etc.

I was told to run relays. Just wondering how wire a relay properly to the load? I’d like to use LED Switches so I know when the accessories is on.

Is there a certain numbered terminal on the relay I put the swich on. Gonna use a 12v ign source for my smaller trigger wire

Just looking for a simple diagram. Thanks

Speaking of 4 pin relays; Pins 85 and 86 are the control side. Either can be hot or ground. 87 and 30 are the output. Again using either side. However I always use pin 30 attached to the hot feed (see below in 5 pin relay discription for this resoning.). Attach the LED hot to whichever output terminal is feeding the device. Then it will illuminate when the relay is on. 5 pin relays have an additional pin, 87A. This pin has continuity to pin 30 when the relay isn't energized. When it is energized 30 and 87 have continuity and 87A is open circuit.
