Alright I have all the parts. Got an ALDL/DLC/OBD2 port out of a wrecked blazer, got TCM connectors, and just got an ECM C1 connector for 30 bucks at the dealer.
Now I just need to know how to wire them together. EFILive talks on Class II, not J1939 CAN right? SO I dont need to worry about the CAN/J1939 wires on the TCM and ECM connectors right? I think I only need to do the Class II wires. What wires are what on the ALDL port? I dont have a schematic for that so I dont know whats power, data, ground etc... As I said I hvae ECM and TCM pinouts, but I dont know which wires hook up where on the ALDL port so my bench harness will work.
Any ideas Ross or Paul?
