Tom:

In my stock, non-California '81, here is what I see:

Left plug of double relay:

  1     2    3

  4     5    6

  7     8    9

(Where 1 is closest to driver seat, 3 is closest to
passenger seat.)

1  blue/brown
2  red coming from 6
3  brown ground going to screw that holds relay to firewall
6  red/red to 2
8  red/blue to fuel pump
9  black

I can't find this ground in my '80-'81 Bentley wiring diagram.
I don't have the newer, bigger, later Bentley handy to check.
