"911.617.136.00" Hmmm.
I went looking for mine. The Bentley manual did not say where the relay is located, but did give the ground location (mid dash). From there, I found this relay; (911 618 102 00) behind the gas gauge.
Traces 86 & 85 are the correct traces to controll the fuel pump; and I don't think I have a factory alarm. (The only other thing that would be controlling there.)
Did they change this in '81? or am I just looking at the wrong relay? . . .
