This chart covers most of Wema's senders, past and present. It isn't exhaustive — the most common senders are shown — so if yours isn't listed, get in touch and we'll be happy to help.
When you contact us, it helps to include a photo of the sender, and to note any identifying numbers stamped on the sender head.
Prefer to work it out step by step? Our guide to identifying a replacement Wema sender walks through type, resistance, length and wiring.
Still not sure what you've got? Send us a message with a photo and the head markings, and we'll identify it for you.
