    OK, I got an edelbrock 1910 q-jet with the electric choke and I am wondernig how its supposed to be hooked up. Do I just need a hot wire going to the choke on it or is there a special way to do it? My old q-jet just had the heat riser style choke and the edelbrock 1406 carb I got on there now has an elec choke but i dont have it hooked up.

    one easy way to do it is this....
    The plug coming out of your alternator that has two wires (one bigger and one smaller), splice your choke right into the smaller wire. This wire only has power when your vehicle is running so it works great for a choke wire....and it's already right there. ALl you need is a female spade, a butt connnector and a 6inch piece of small guage wire. If your edelbrock has two terminals...then ground the other side to the base of the intake....between the carb gasket and the intake plenum.

    second most easy/recommended way: conenct to IGN port on fuse panel and run a 10 amp fuse inline in wire along the way somewhere

    as long as you have power to it all the time that key is on then youll have it connected same way factory connected it

    The proper way to set up the choke:

    1) Unbolt the electric choke housing
    2) Remove the choke blades
    3) Place all parts in plastic bag
    4) Place plastic bag in garage behind stockpile of used oil.

    My 83 has a switch so choke voltage is only on when there is oil pressure. I'm not sure how closely the alternator idea approximates this. I think the reason they do this is so the choke isn't heating up when you are cranking away but the engine isn't running. There might be other weird cases too, like if you are listening to the radio with the engine off.
