Carl,
I think I have the following right. But I have never wired an electric
pump. If my base assumption is wrong, somebody will jump in and say so.
I do not believe there is any "ignition on" power going into the fuse box.
Every circuit there is either always hot or controlled by "ACC" of the
ignition switch. The ignition wire off the ignition switch (Shop manual
says it is 14 B/P.) goes to an in-harness splice under the dashboard. From
the splice wires go to the ignition coil and a few other places (like the
generator light). To get power switched as you want, you need to tap into
one of the wires going to/from that splice. If you tap into the one to the
coil inside the engine compartment, get onto the switch side of the iron
resistor wire, not the coil side. If you are reusing an old under-dash
harness, I suggest opening up the existing splice and redoing it to add your
wire. Those splices have often deteriorated from age and are a source of
power loss.

G’day from Australia to everyone and happy new year,
Hope someone can assist me with the following?
I Imagine that many of you will have fitted electric fuel pumps to your
Corvairs and if you have then perhaps you might be able steer me in the
right direction with the following question.
I am the final stages of installing an electric fuel pump in to our RHD 1965
Monza convertible.
I say ‘final stage’ as I have to date, mounted the electric fuel pump
securely under the car close to the fuel tank. Have carefully connected it
to fuel tank and fuel lines, installed all the needed wiring and included a
oil pressure and inertia safety switch’s.
The last step I have yet to complete, is to connect a wire to an “ignition
ON +12 volts” supply.
Looking at the factory fuse box in our ‘65 Monza, the only connection point
that I think might provide an ignition ON 12 volts supply, is the the fused
connection for the windscreen wipers. It occurred to me, that this might
work, but of course if the windscreen wipers also function in the ‘accessory
position’ of the ignition as well as the ‘on’ position then I this
connection point will not work.
Questions:
1/ I know it’s a simple question, but do Corvair wipers operate in the
ignition switch ‘accessory’ position?
2/ If the wipers do function in the accessory position and I can’t of course
use this as wiring point. If this is the case, can anyone suggest an
alternative easy to access point to wire my electric fuel pump to?
Hope I have explained the above well enough and hope someone can assist me
in completing this electric fuel pump installation.
Regards from a hot Australia. It’s summer ‘down under’
