1. Run a switched 12 volt wire to the electric choke. It's best not to tap into the ignition power directly to do that.
2. The ECM controls the EFI injectors, ignition timing advance, transmission torque converter clutch lock-up, and fuel pump power. You need to power the fuel pump via a switched 12 volt source, provide a means of locking up the TCC (a search will show you the options there), and take the bulb out of the SES light.
well how do i wire the choke then i have no idea what a 12 volt switch is or waht wire on the car i can use to make the choke work im not good with electricity.
