Electrical Under dash plug Identification

[skiwesser11]

Car is an 88GT, no standard power windows. The stock amp was removed long ago when I had a 90s “system” and I didn’t know what I was giving away, now aftermarket radio(s) sound like crap (I think they had an amp under the dash?) and have horrible reception but antenna wire seems fine? At any rate I’m thinking maybe the long light colored plug is stereo related?
Any one know what these are??
tia!!

I believe that plug is for the 2.3l fan controller. Not used on the 5.0

would need wire colors for the black one. It’s either the low oil relay plug, or convertible top relay plug

If it’s the “low oil” relay plug then it should be plugged in correct? If it fit convertible top then it make sense... oil pressure gauge moves but low oil light hasn’t come on in a long time if ever, but it’s never been low on oil either I don’t believe... thank you!!

Yes, for the low oil light to function the relay needs to be plugged in and the sensor installed in the pan. Those pan sensors tend to leak, so they are frequently deleted.
