4 Pin 12V Automotive Plug n Play Deluxe Relay Harness Socket with 48" Wire

AutoLoc's relay pigtail socket features 48” long leads to complete your job without the need to splice wires, allowing you to place the relay in the best possible location. The heavy gauge wire allows you to handle up to 30 amps rush and 20 amps continuous power making this perfect for almost all your 12 volt DC accessories that do not need the normally closed (NC) circuit.

AutoLoc's heavy duty relay sockets make your installation a snap! Our pre-wired relay socket is ideal for use with door popper, shaved door and trunk solenoids. It can be used in several additional applications including radiator cooling fans, horn relays and more! Plugs into 5 pin relays and works best on any single pole double throw (SPDT) relay but will also work on a single pole single throw (SPST) relay.

We recommend the use of AUTRA1000 - AutoLoc 30/40 amp single pole double throw relays (SPDT). This socket lacks the Normally Closed (N.C.) wire, which simplifies the installation in applications that do not require it. For relays that require the normally closed circuit please use AUTRAS12.

Each plug-n-play socket includes heavy duty 14 gauge OFC copper wires, plated terminals, and high impact ABS plastic base.

Yellow Wire = Pin 30 12V Power Supply
Red Wire = Jumper from Pin 30 to Pin 85
Blue Wire = Pin 87 12V Power Out when Relay is Energized
Black Wire = Pin 86 Negative Signal (from Keyless or Alarm)
*Using the red jumper wire makes relay operation possible with just 3 wires.
