Electric Choke Wiring, Smartest way?

[Richard Dobson]

What's the smartest way to wire up a electric choke on a V8 with a Edelbrock 4 barrell?

[msgross]

I wired mine to an ignition hot plug in my fuse block.... It should be ground to the carb holddown nut.....

I click the key on, wait a few seconds for the carb to react and fire it up....

The factory, on the later model cars, ran the hot lead thru an oil pressure switch

[Richard Dobson]

Where on the fuse block do I put a wire with a terminal that goes to the electric choke?

[71tahoe]

it should say ign unfused probably with an arrow pointing to the spade clip

[Richard Dobson]

Does anyone have pictures of a fuse block to show where I can locate a terminal for the electric choke? I hate to be a pain in the keaster but it sure would help. Thanks

One of these should work for ya.... I circled them in red... just run one wire to this connector and ground the other terminal on the choke to the carb mounting bolts and you're set. I ran my HEI off the other terminal and fused both of them....

borrowed pic, not mine.

If you are running an HEI just use your old coil wire.

The electric choke needs a full 12 volts to operate properly. The old coil wires have a built in resistance to reduce voltage to 9 volts to protect the coil windings. A common source often used for the choke wiring is the hot wire to the wiper motor. Any key on 12 volt source is good but I would run a fuse in the circuit.

Vette, did not know that, I have my Jeep wired like that. Will have to fix. Thanks

I used the power wire that originally went to the Transmission Spark Control System. I removed the system and the power wire was already at PS of the engine at the fire wall. One butt connector/heat shrink and I was done.

I pretty sure I'm using the same TSC wire. There was a wire under the hood that was clipped off - the TSC was long gone by the time I got the truck. With a test light I determined that the TSC wire had 12V with the key on and nothing with it off. Works like a champ and its already only about 8 inches from the choke.

I ran my HEI off the other spade that I circled in the picture... True about the old coil wire... You can remove the white resistance coil wire at the bulkhead connector and replace it with a new 12-14g wire....

[Richard Dobson]

Could one of the (2) blade terminals that are right above the fuse on the bottom right be used for the electric choke. Since I don't have a battery in the truck yet, I guess I need to put one in and check the volatage with a multimeter on the (2) blade terminals, right? I wll try to show a picture of my trucks fuse box. I do have a HEI dist on my engine. Which wire is the one for the coil that you said I could use if I change the resistance wire to a 12-14 ga.?

[msgross]

the wire that runs from the coil to the backside of the fusebox is the resistance wire. It takes the voltage down in voltage. I think its usually white.

it also looks different. IIRC it has a woven insulation. you need to remove the bulkhead connector(3/8" headed screw) and remove the wire with the spade connector otherwise you will still have resistance.

I have seen some people run a new wire through an empty hole on the bulkhead connector.
