Following from the previous post https://honda-tech.com/zerothread?id=999211 I have removed the brackets (with 4 bolts) the holds the ecu. I see a flat box with 4 screws at the corners and a center screw. There at least 4 sets of wires connected to the bottom some 20-30 wires in total. These wires have a common sleeve that holds them in place. I cannot find and jumper leads anywhere? Are inside the ECU box? I would not have thought so. Is there a point where I can connect an OBD to in this car? Where would it be?
Thanks very much in advance,
James
