So I took out the harness looks like a part # 1m5t-12a690 not all the tag was there but when I disconnected the gray connecter my volts obviously dropped to 0v with koeo , and my tps went to 17% . I did find someone replaced the upstream o2 connector because the wires where just twisted together. I fixed that but I don't think this is where my short is. I don't want it to be the harness to the PCM. I didn't find anything else in the harness I pulled except it smelled of antifreeze.
