Review on 🚗 Enhance Your Vehicle's Efficiency with the Directed Electronics Inc 528T 12v Accessory Pulse Timer by David Golden

But I got it working for my application which consists of turning on an electrical load (electric marine toilet) with a momentary switch (button) and letting it run for x seconds before turning it off. This wiring order (and nothing else I've tried) worked for me: Yellow + Red + Battery positive -> Black with white stripe button terminal. -> other momentary switch terminal Black + ground/battery negative -> load (electric toilet in my case) negative brown -> load (electric toilet in my case) positive orange - not used Blue - disabled
