Hey guys, I finally received my 5.3 (from a wrecker in Texas, I'm in Winnipeg) for my turbo Malibu project. It looks like some of the wiring harness is missing, particularily the injector harness. Here's a few pics does anyone know where these plug into? I think the big rectangle plug with the bolt in the center plugs into the firewall/cab harness. What about the rest? Is one of them for the injectors?
