Convertible Top Control Unit wiring...

[levdeb]

Hello!

Got this random wire that is coming from my cab top control module to my oil pressure idiot light. Its not in ANY wiring diagrams, and isn't supposed to be there.



So my question is, what is the Hd pin for? I have the green wire going directly from that pin to the light...

I'd like to get my idiot light wired up correctly, but the previous owner (who passed away) must've wired it this way for a reason..?

Thank you for your time in figuring out this very random issue!!

1988 930 Cab.

Best,
Bill
