Just a quick one here...Where are those, that have them on their carbs, wire the Red wire to. I am currently running it at the positive side of my Ballast Resister...not spliced in which I am assuming is a Positive Ignition point, as specified by my Demon/Holly carb's instructions, and the Ballast Resistor is not wired up directly because of my ECU from FBO Systems for electronic ignition...but I am not really happy with that way. I can run a wire from the choke to the actual positive pin on the ignition switch yet I would like to find a more closer point if I can. Otherwise I do have a number of positive ignition points for use besides that also. I do not have to splice into the existing wire harness at all as I have several electrical buss' that I am also using for my extra gauges and my Tach. Also as well I have an extra buss on the firewall that is used to power the buss' under the dash for the gauges. Thanks for the help...cr8crshr/Tuck:thumbsup::usflag:
 
You want a source that is only hot when the engine is actually running. Most go to the alternator. I forget which one but one post is only hot when the engine is running and not just when the switch is on. Easy to find with a volt meter.

Thought about that one but specifically the manufacture of the Carb specifically states "To a Switched Ignition source" which I think does not include the POS side of the Alternator but I could be wrong...cr8crshr/Tuck
 
It goes to the ignition side of the ballast normally, if you bypassed the ballast anywhere in that circuit should be fine.
 
An electric choke can draw up to 5 or 6 amps. Because of this, it is better not to wire into the primary ignition system (can drop the primary voltage, which will affect the secondary voltage), but rather almost any other switched 12v source. If you wire into a non switched source, you will draw a lot of power and kill the battery.
