Hi everyone, I'll admit I joined because of a question I have. This post is a long one so sorry about that. I couldn't see a new member introduction section. I couldn't really search for anything in here regarding my question since I'm not sure what words I want to look for I tried the letters on the PC board in question but that yielded nothing.
So my issue is this: I got this timer circuit on ebay:

for an led light(it's a 12V truck clearance light) in the garage for a parking guide. The minivan's bumper hits an upside down radio antenna which closes a switch to turn the light on. It's powered by a 12V power supply that's always on, for my car stereo system I have setup in there. You have to back the minivan off the switch to turn it off. If I go real slow, and just barely move the antenna, I can put it in park and the minivan will roll back within the limit of the play in the park pawl. If that's not enough I can just put it in gear and park again to roll another couple inches back. I can't back off much more though, or I'm into the door. But that's not my electronics question. I got the timer so we can leave the minivan pressing against the upside down antenna and exit the minivan and go into the house and drink coffee or jump on the beds or beat the kids, and let the timer turn the light off after a set time such as one minute. I'm not bothered too much about how much time. It's adjustable. this device claims to do what I need, resetting once the switch opens again. The problem is that it didn't come with any diagram or any paper whatsoever. That means I have no idea what terminal is what. I can see the screw terminals are the NO and NC contacts of the relay, and I have tested just the relay, but there's nothing to indicate what terminal is for powering the device, where the switch(or button) would go, etc. You can see 3 2 prong terminal points. it came with a jumper for one of them in the bag. I believe it's for selecting between two modes, that is, two different time ranges for the timer, but I don't know which one it would go on. I have found similar devices online that look identical except all the terminals are screw types like the ones for the contacts, except for one which is a white plug. None of those ones show any diagrams on their pages either. I have asked the vendor and am awaiting a reply. Does anyone know the terminals of this thing?
