i have swapped a 13b n/a with manual trans from a 1988 fc convertible into a 1988 fc hatch that had a na aswell and a auto trans. everything is in place in order to just fire the motor: but when i hook up the battery with no key in the ignition. the starter relay begins supplying power to what sounds to be a vacuum in the throttle body. im new to all this so this is really my first time with electricals. so i can use any help possible.
