Steben Hi, I've been reading through the threads recently and came across info on 5 pin relays which were pretty much obsolete . The wiring can be altered to use the more common 4 pin and i wanted to change mine hoping to avoid issues before they arise! I pulled them today to clean and check and they are fused 4 pin. The fuel one was discoloured around the 2 main terminals and when i googled the relay they are common stock. Is it only the 851s that have the 5 pin ? Cant see any obvious wiring alterations. Cheers.
Steben Thanks Matthib Since that post I have changed both relays for the 4 pin and all's good, keeping old ones in tool roll in case. Cheers. As the link says it looks like the 851s were 5 pin.
