Right.

Most car electrics I am getting the hane of, but I have a selection of 5 pin relays the main difference is the 87 a or 87 b middle pin.

Before I go mad ( ok madder then ) what is the difference between these two types of relay.

oh picture of the layout



5 pin relay

many thanks agriv8

Hi,

They appear to be different relay types. 87a is a changeover relay (when 85 / 86 have power, the output switches from 87a to 87)

87b is a relay with two outputs, it appears, that join 87 and 87b together to 30.

Diagram probably better
