I can't figure out how to get pics on here, but I have an ecu that has 4 plugs on it. One 26 pin, one 16pin, one 12 pin, and one 22 pin, in that order from left to right. It has a foot long section of the harness still attatched to it.....serial number on it is 37820-P72-901803-100565. The writing on it says its a b18c auto ecu, not sure about the year tho. I think its obd II but the wires dont match for the pinouts i've found. Plus there are for plugs, and the auto might factor in too. Any ideas on how to figure out these plugs and pins ? JDM pinout? schematic or something......any help would be great......thanks........
