fast delivery, good products, best quality and services. thanks to Funny.

After receiving the relays I tried to figure out the attached installation diagram, but to no avail. I reached out to the company to provide an easy-to-understand installation manual, but so far there has not been a reply. Alibaba should request every company member to include installation manuals that are easy to understand and write in the product the name of the manufacturing company. Accountability is essential in global trade.
