This relay has a multitude of uses and has been original equipment on many cars and trucks going as far back as the mid-70's. If your car uses one, I suggest buying one and keep it in your glove compartment. Parts like this never find a good time to fail and you'll be glad to have it. If you're already buying something else, for $2.40 you can't go wrong.
Just in case anyone needs this:
85,86 = coil
30 = common (swings between 57 to 57A on energize)
57 = norm open contact (not energized)
57A= norm closed contact (not energized)

Make sure to add some form of back EMF suppression or these relays will damage sensitive electronics. Use a 1N4004 or higher voltage diode connected such that the diode conducts the back EMF of the relay coil when power is removed from the relay.
I used a pair of these to switch the power door lock actuators (CAT# DLA-1) when I installed power door locks in my 1995 S10 that didn't have factory power door locks. This way, I can install a remote starter/remote door lock unit later. The remote units generally put out only enough current to fire a relay, not the actuator, so this will work perfectly. Order the plugs (CAT# SRLY-2) to make installation easier.
The local auto parts store wanted over $9 for an equivalent relay. Do yourself a favor and order half a dozen of these to have on hand for projects. At this price, it's even cheaper to use these than to buy SPST relays at the local store for your fog/driving/off-road lights.
