Red Headed Stepchild-75 Swinger LSX Swap

Smart get rid of that connector. I'm doing whole new engine side harness all new components. I'm not going modern yet like you. For a resto hot rod like you have done and time investment I think it's smart!
The only reason im doing it myself is I can't afford $135 an hour for wiring out here. So looks like I have to suck it up and get out there. I hate doing wiring but I know how to do it the right way. And this time I'm going to.
