Fuel Pump Relay, part number and where to purchase?

[IS300E30]

So, I bought this relay (part number 61311373585) as it seems to match up with the current fuel pump relay that is installed on the car:

What I received however was part number 61-36-1-378-238 which is an orange relay and I believe is the O2 Sensor relay

I started doing a little bit more searching, and I stumbled on to here:

https://www.fcpeuro.com/products/bmw-fuel-pump-relay-genuine-bmw-61368373700oe

Which says "1987 BMW 325i
Originally produced as a 4 prong relay, it has been superceded to a 5 prong relay."

Now, I am lost on what the correct relay I should get. Currently the fuel pump relay is a 4 prong relay on my car.

12 63 1 277 245 - this is what my catalogue lists for a 1988 BMW 325is, which I do not agree with. The pins are in the wrong locations and RealOEM lists it being for a euro spec E30.

e30austin, thank you for the quick reply but when I pulled that part number up it looks a lot different than mine. Might be that mine is an 87 and has 2 fuel pumps? Not sure.

Very interesting. I even pulled up RealOEM and they are also giving me the 5 pin, main DME relay, for the fuel pump...something weird is going on.

The part number ending in 585 is the correct unit, for the fuel pump relay.

Maybe the green one? Per the description, the 5th prong goes into a blank slot so it is not being used anyways. Does this seem right?:
