Default 84 Electric choke wiring

I have an 84 Corvette that was converted to 4bbl.
What is the best place to get my 12 volts from for the electric choke?

Is this a trick question ?
How about the ignition circuit.

Not hei.
Ignition circuit means the circuit or circuits that power up when you turn the ignition key to the run position.
Typically this wiring is color coded red on gm vehicles.

Not so!





OP - What carb? Brand & part #? Most after-market if electric choke is an option offer a kit. If it's snagged from an OE of some sort an attempt at a wiring diagram/function for that OE.

Use an oil pressure switch so choke only operates when engine is running. You can run a fused wire to the from under hood electrical center to one side the other to choke coil.

GM actually did use a wiring scheme and the OPS. I do think the OP could provide much better/more information.

Ignition feed wiring is typically red and battery feed is typically orange. Not always, but when your forced to improvise (like when you put a carb on a fuel injected car) sometimes you have to make decisions that are based on imperfect information.

If you really want to get into it you could probably get the choke light on the warning light panel to come on when it's on too...

This is a 'typical' ignition switch scheme for early Saginaw column. Anything you see in RED (top) is either a alternator or battery feed. 'imperfect information' - I'd think only supplied by yourself.

Yes you could and it might be a good thought!!!

Go start probing red wiring on your car that is not obviously battery. You will find out that most of them are ignition circuit.
You might as well claim ground circuit wiring is not typically black, turn signals are not green or yellow, solenoid post wiring is not purple ect ...

Since the OP has an '84, I thought it might be good to see an '84 Ignition Circuit diagram. (Note the Red wiring.) I'd think a good place to connect that choke wire would be to the fuel pump circuit.





(Pardon my personal scribbles.)

I like the fuel pump circuit idea, provided its still intact.

Perhaps the easiest way to accomplish this would be to purchase a Packard 56 terminal (local NAPA or many others), release the terminal
from the connector and crimp the 'new' wire as well as the original wire into the terminal to create the splice.

Really 'simple'!!

Thanks everyone for your replies. I learned a lot especially about Packard 56 terminals which I could not find. I took the suggestion of wiring to the batt side of the distributor with an inline fuse. I soldered to the batt wire and covered in heat shrink.

Thanks again
