This is a wiper motor park relay. It looks close, maybe some stuff busted off? The wire tabs would normally stick out of the housing. How many wires on your wiper right now? Does your wiper motor park properly?
What is this?

Sorry, not to sure what you mean when you say "park properly" :?:
Does it mean where they settle when they are turned off :?: If so, then yes they do

Yes, "park" is when they shut down and slide down into the "rest" position. The relay shifts a dog that pulls the wipers down farther than when wiping and keeps the motor operating until they are in the right spot, then shuts the power off. What's on the backside of that part?
I'm still thinking it has something to do with an alarm, like the motion detector....if you have a multimeter put is on the continuity setting and see if the two connections set it off when shaking the part..it can't be a relay with only two wires
I think Pontiacgp is on the right track here. The theft deterrent system has 7 wires; Black: Hood switch, Yellow: Alarm arm, Light green:Key-door unlock and alarm disarm, Light blue: Alarm, Dark green: Arm indication, Black-white: Alarm output, Pink:Alarm arm abort.
Like I said earlier, I can trace the color of wires (most of the time!), I just can't tell you witch car or year of car for the different circuits.

It could very well be a relay. Two wire relays are common in computers and appliances. A ptc relay is one example. It works as a switch with resistance and doesn't transfer voltage to the other side of the switch until enough resistance (heat) has built up, this way full and constant torque in electricity is applied at all times (to the device/motor) regardless of temperature, weather, and voltage/amperage differences in the wires or charging circuits. This could be how the opposite NTC relay works :?: I'm no electrical engineer but you can kind of gather how they work
I'm not saying that is one I've never seen anything like that in the picture, but it could be a relay just as well as anything else. I'm sure 2 wire relays back then were much bigger than today.

you won't find a ptc relay in a vehicle so I don't even know why you would mention it and no cars of the 80's ever used a 2 wire relay...and the common 12 volt relays we use today are no different then they were back in the 80's. Vettes came with factory alarms in the early 80's so who knows what the original owner ordered for this car...
