Fuel gauge points straight up

[J <sundiver@xxxx>]

I just got my car back after months of being in the shop, and now
the fuel gauge just points straight up. Since among the things replaced
were the fuel pump and throttle cable, I think its most likely that
they knocked a wire loose somewhere. The ones going to the sender
seem ok.

Can anyone tell me which wires under the dash go to the fuel gauge? Its
not at all obvious to me, either from the service manual or from sticking
my head under the dash and trying to trace the wires. I understand the
ciruit. I just can seem to match the wiring diagram to the physical wires.

I could just take the car back to the shop and tell them to fix it,
but I've been without the car far to long already.

Thanks.
