Review on 🔌 Holley External Vacuum Electric Choke Kit by Vincent Pavelko

is a pack for twin pump 4150. Contains everything you need. installed on 4779 with open hanger for hand throttle. If you have previously removed the choke from the air horn for "more airflow", you will need to reinstall it as this kit is designed to convert your existing manual choke to an electric one. I added heat shrink tubing to the spade connector to connect the +12v to the throttle body cover for added protection as the base of my air filter is metal. Solder the included red wire and shrink it into the existing +12V ignition on circuit on the firewall. A pair of needle hose pliers will help slide the tiny retaining clip onto the choke stem. Found out the hard way that the choke rebuild kit for 4160 vacuum secondary carburetors doesn't work on twin pumps, yes. Internal piping, passageways and critical vacuum openings in throttle bodies are different.
