Chevrolet switch plate - last version with 6 switches

[Jacques Reed]

Hi Mariano,

Nice photo of the Autopulse electric fuel pump.
I thought I would have a look at my original ignition switch tails again to figure how the Autopulse was wired up.

There is a doubled up red and black wire from the ignition switch. One goes to the resistor but I was not sure where the other one went. Wiring diagram states:
"No. 45- ignition switch to lead from Autopulse pump"
"No. 46- Autopulse switch to Autopulse pump"

Could not understand why there would be two leads to the Autopulse the way it read.

I believe No. 45 may just be a jump to the input side of the Autopulse switch as per attached diagram. With that arrangement one cannot run the Autopulse without having the ignition switch on. This would be a good safety feature. One can still start the engine without having to run the Autopulse, a valuable feature when not needed. It sounds very simple and perhaps that is all it was.

Would be interested to hear what others may think.

Cheers,
