I am finally getting around to hooking up the wiring on my electrical choke on my Edelbrock 1407. There seem to be two schools of thought on how to hook it up. One hook it to the coil. Two hook it to the Ballast. I was curious to get the boards thoughts on where the best place to wire this into? Is there a more logical place that I am missing?

Whomever told you to hook it to the coil is wrong.

The choke wants 12V, the coil doesn't get 12V. Hook it to the ballast feed side.

Read Edelbrock's instructions on proper voltage for the choke and you'll see.


They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.

I'm assuming it's the same on any electric choke? I'm almost sure. I ask because I'll be doing the same soon with mine as the OP

What Supercuda said & easiest/neatest is to drop a short line down from the choke several inches & T into the blue alt field wire in the loom that is running alongside the inside edge of the pass valve cover

The double blue wire on the ballast resistor is the most convenient source for the electric choke. Just use one of these to piggyback the spade terminals.

That sounds like a pretty simple solution. Any idea where to pick one of those up?

NAPA has em, I'd call your favorite parts house & give em a descrip (brass electrical tap, double male/single female 1/4" terminals) might not be the exact definition but close enough

Yep I agree with all these guys and this is a nice Idea John posted. And as Supercuda said you dont ever want to hook the electric choke to the coil. Good luck to you.

None of the above...

Power it through a relay triggered off the 12v line at ballast.

Seen too many brown or dark blue wires burned up in the under dash harness.

I did the field wire (switched 12 volt) trick on mine and so far no problem. E-brock does not want you to tap into the battery wire off the alternator because the voltage can be too high when charging.

Plus the battery wire on the alternator is hot all the time.

The triple tap works but is very unsightly. A short line T'd down into the loom is aesthetically pleasing (& looks OE). Yes it'd be better to relay any and all add ons (& even the existing headlights/AC/heater) to the alt batt stud (my preference/keeps the ammeter honest) but barring that (addition) I'd just clean every terminal/connection expecially the bulkhead & do Nachos bulkhead parallel bypass & call it good.

Not so bad if you bend it 90°.

I don't see the running current draw of the choke coil (around 1.5 amps) as a big issue, not high enough to overload the wire.

They had to order the part from the warehouse at orielly but I got it all plugged up this afternoon. Still have a couple more things to hookup before I get to start the engine so I will have to wait a while to verify everything is working. Thanks for the help guys.
