What's this relay for??

[fivetenguy]

Hi. I'm getting the engine bay, along with the wire harness, ready to do an engine swap in a '72 510 wagon. I noticed my other '72 510 2 door did not have this particular relay anymore (also engine swapped. KA24DE). I looked in the wire diagram, but could not find this particular relay.

 

Can you guys help me identify this one? I'm guessing it's not needed since my other 510 doesn't have it. The wires on the harness are the same color as in the pig tail. Wire colors are yellow, black, blue and white/blue. If I recall, this relay sits on the right side of the engine bay. I don't have pics of its original location.

 

Thanks

Is there a XXXXX XXXXX 10 digit part number? Possibly starting with 252XX-XXXXX ???

I'll look for it tonight when I get back from work. I couldn't get any numbers off the cover of the relay. I'll look under it to see if there is anything.

Looks like the electric choke relay (72-73) - wires are correct for that.

Here's the wiring harness connector on my '72 wagon.

That was my guess but my diagrams are for earlier cars. Often wiring is the same between models but the 620 auto choke heater relay didn't match so I left it.

 

Get me the part number.
