hello mustang world

so I have 1989 coupe I'm trying to figure out the relay itself I need to test it. i was just going to buy a new one there only like $15 . now my issue is the one that I bring to the auto parts store has 4 prongs and everyone they carry for a 89 5.0 mustang is a 5 prong. when I look them up on line there all 5 prongs . it appears to be a original ford (green ) relay . I have not gone to ford yet that's my next move.
I typed in -how to test a ford mustang 5.0 fuel relay - and it brought me to a site that explains how to test the relay connector (the female end) and the site appears to have 4 wires leading to the connector on the site... so if anyone has a 89 coupe could they check there stock(I think) fuel pump relay please I know it is a pain to get to ..thankyou very much

Relay consists of a load and set of contacts

Find the load, it has resistance once you id the load the other are contacts

That easy

Looking at the terminals inside, I would guess that 1&2 would be the coil inside and 3&4 would be the switch.


Just a guess, dont shoot me.
