Relay CM1af-12V ACM32201 (Pack of 2) – SPST 12VDC 4-Pin Automotive Micro Rela…

I like that it has a nice touch of being unbranded/general, so you can add your own labeling.

At 70*20*18mm / 2.75*0.78*0.7", the relay is hand-friendly during install.

What stands out about this relay is the P7TFOS16 code, which makes replacements straightforward in a pinch.
