Wiring Accessories With a Relay

Hey guys,
I’ve seen quite a few questions recently asking how to wire accessories,
I recommend using a relay for each accessory,
Heres how its done;

Notes on this schematic,
1…Ignition powers the holding coil in the relay thru
a switch, this does two things, (A) once the ignition is
turned off the accessory will be powered down, no chance
of a accessory being left on. (B) The holding coil only
draws approx 150ma so the draw on the ignition circuit
is negligible.
Of course the accessory is also controlled with the switch.

2… Looking at the wire chart below 12 gauge wire in most
cases will work for our UTV needs.

3…I fuse each individual relay and accessory, for example
I have two light bars, each one has a relay and is fused separately.

4… See below for a pic of the relay depicted in this schematic,
these relays can be purchased all day long on ebay for $2.

5…I crimp, solder and heat shrink all connections.

6…These relays are considered "N/O" (normally open)
once the relay is powered it then closes.
