I bought a Complete running 93 bronco 5.0, auto, 1356. Motor runs good an transfer case is bad. I put my C6 on the motor and pulled the complete wiring harness inlcuding the interior harness with the ignition switch. I'm getting close to start up and i heard a rumor that it won't start without the harness plugged into the transmission. Is there any truth to this? Any Input would be appreciated. Thanks
