I have a fuel pump switch in '81 non-Westy.  I
could use it as a kill/theft switch, but I don't.
Who would steal my '81?

I installed it to deal with the bug in the FI
system that floods the engine at 10,000' and 20 degrees F,
like after skiing.  I've written about that a couple of
times; look in the archives.

Actually, I installed three switches, incrementally, trying
to solve the problem.  I thought it was the cold start injector
needing more time "on" but that was exactly the wrong
direction.  A second switch to keep the cold start injector
"off" didn't do the trick; the fuel pump switch did.
Because this was experimental, I just ran the wires under
the rubber mats, up under the rear seat and into the engine
compartment via the deck lid.  It has worked without problem
for 10+ years.

In this photo, the fuel pump switch is the one on the right.
Anyone dumb enough to try to steal my '81 would never figure
these switches out, but I leave it "on" all the time anyway.
