Units are assumed to be working but I am unfortunately unable to test them. The relays appear different but do share the same part number - my guess is that they were manufactured many years apart. Does not come with anything other than what is shown and does not come with any accessories.

Unfortunately, I cannot offer any returns on this item and it is being sold as-is.

Feel free to ask questions; I will do my best to get back to you within 24 hours. Thanks for looking!
