I have a 165 ECU wiring harness that I am fixing. It has been hacked up pretty bad by the previous owner. I am in the process of repairing it and I am mostly done. I have some questions about the grounds on the wiring harness. Based on what I can see I can just combine A12,D1,D3,D6,D10 together and ground them with a ring terminal? My second question is A11 and D2 do they need a ring terminal inline and ground to the engine, or can I just run the wires straight back to the ECU?
