Does anyone know what this component is? I can’t find a illustration in my 1987 Thunderbird/Cougar Wiring and Vacuum Hose guide. It is located on the passenger fender, under the air box routing. Thank you.

Well that is a relay. Though I'm not an expert with pre mn12 tbirds. So I don't know what that relay does specifically.

Feel like thats a service port for something like ABS or Diagnostics for something. Lemme go grab my old manuals and see if I can't come up with something for ya.

Maybe you can make some sense of these
. And as Matt asked, whats the color of the wires so we can help ta out a bit.

Images are no help when restricted in resolution...peh

Here are the 5 wires, they are rather beefy gauge. It is a relay.

Hey, any chance it’s the WOT switch/relay fir the AC compressor? Here is a page I found in my 87 Wiring book, and a closeup of the diagram that has some of the wires in the picture I sent.

Sure looks like it could be that. You can do a simple continuity test with a multimeter between the PK/LB at the relay and the Clutch pressure cycling switch.
