Switching to an elec choke is pretty simple. You'll need the assembly to swap out(it will contain the plastic body as well as the bimetallic coil found inside) and then you'll want to wire it to the "S" or "Stator" on the back of the alternator. There's a couple reasons for this. First, you only want the choke action warming when the engine is running and not when the key is set to the "on" position. Simply wiring it on a circuit live when the key is switched to "on" can cause your choke to fully disengage if you leave the key on for a while for any reason before starting the engine. Secondly, it provides a lower voltage signal so it allows the choke to operate more slowly. You don't want the choke disengaging too quickly or it will outrun the engine's need for it.
