Need help understanding how to wire up one of these motors....I purchased a painless kit (#10206: 18 Circuit GM Truck Chassis Wiring Harness 1967 - 1972) for my previous project but never used it...I have the engine from a 2006 truck. It came with the motor wiring harness. My question is, how does the harness from the engine connect to the painless one? Can i even use this painless kit? Is there another painless harness that joins to kit 10206? I'm a little confused. Thanks for any clarification...
