Shop by your vehicle Close. I need to wire an electric choke on my carburetor.
Where can I pick up a feed to do this? Unfortunately, this can be a bit confusing and also a bit lengthy.
Installing A Manual Or Electric Choke On A Holley Carburetor
Many and later harnesses already have a fused 12 volt feed in the harnesses that were used to power up things like idle stop solenoids, TCS spark controls, turbo kickdown power, etc. If you are fortunate enough to have one of these harnesses, you can usually just tap off of one of those feeds.
If you have Factory Fit harness earlier than , you most likely do not have a fused volt fed wire already in the harness. If you would prefer, you can also tap into the windshield wiper feed wire, as that is also a volt ignition fused circuit.
What you do not want to do under ANY circumstances is take power from you coil or main distributor feed. Two reasons for this: That circuit is always unfused and you do not want to wire an electric choke to an unfused circuit.
Most stock primary ignition circuits are wired through a resistance wire, which only allows about 8. This would not be enough voltage to properly operate your electric choke. When using any of the other American Autowire wiring KITS such as a Classic Update, Power Plus, Highway, or Builder Series, you simply need to take any ignition fused 12 volt feed use about a 10 amp fused and connect it to your electric choke assembly. Some AAW products actually have a wire already allotted for an electric choke, so watch for that in your instructions.
This will generally be outlined in the engine connection area of your instruction set.
