Review on ⏳ 996152131 12V Delay-On-Release Black Time Delay Relay by HELLA by Rovy Oppeneer

Works great as advertised. When they check their reviews they must get a little diagram of the very specific wiring that needs to be done; In contrast to normal relays, this is like the old German flasher relays, which have to have a certain voltage, positive or ground, on certain connections in order to work at all. The timer must internally have a positive and negative output on specific terminals or it will not latch and this makes it a positive trigger only relay. So if you have a negative trigger switch you need to use another relay to reverse the trigger polarity. You can show it with a simple flowchart and a few words. And found other people on google with the same comment but they mentioned the positive placement of the battery power but not that the negative also had to be on the specific connector or it would have been 5 stars.
