If that’s the number that is on the relay, that’s a engineering number not the parts number. If you are friendly with your Ford dealer parts guy see if he can help.

? its a ford relay. that number comes up as a part number but is then crossed to a 5 prong relay. want to make sure i get the right one. i called ford and the parts guy laughed at me when i asked him for an 89 part. said all parts were obsolete. local parts store cross referenced that number but came up with a 5 prong mine has 4. LMR has the same 5 prong and states that the 5 th isnt used but is the correct relay. wanted to get this relay asap cause i cant drive the car without it obviously. if i cant get a part number asap i guess ill have to order it from lmr and wait for it. the shipping is terrible in the current times as it will come from tx to nj. wont see it for 5-7 days at the earliest. surely someone on here has had to replace this thing in the last couple of years and has the newer part number ?

You can always run a 5 prong relay in place of a 4 prong. All the relays in my box are the exact same 5 prong, even the horn.

IIRC, the extra prong is for an action to be taken when the power is off. It's just ignored.

Old part numbers are often still on shelves or in boxes at dealerships and warehouses. There used to be a computerized phone hotline my dealership used to look up NOS parts. I found a brand new part I needed was in the dealer’s attic when I called for my own car. The system may have been killed by the internet, but checking for stock at other dealerships should be easier for a good counter jockey.
