Im new to this so bare with me blah blah blah, im tryin to make a stand alone harness for a 96 lt1, using 96 caprice harness, have power to injector fuse, and pcm, also power to the fuse block its self, i cant get a scan too to communicate with the pcm, i have voltGe at my uart line, power to dlc, both grounds. I only have 73mV at the class 2 line, thats probing at the pcm, i feel like im missing a voltage reference somewhere im jus not sure, this is all i need to drive my car, this is my first build, ive gone from headlight to tail light on this thing n i really wanna enjoy it, any help would be more than appreciated
