1987 Mustang LX 5.0
One is a fuel pump relay-E3TB-9345-A2A
The other is a EEC power relay-E3AF-12A646-B2A
Another nearly identical EEC power relay I have has almost the same number and fits the socket-E3(A?)12A646-B1A/7ED
Unknown application Ford relay-E4LB-13A025-A2A
I am assuming that is one part number for each but it is arranged in three numbers (hence the dashes) vertically on the case, for space reasons I assume.
