Hello. I'm planning on adding an Autronic setup to my car, but I'd like to keep the existing Honda harness. This will also allow me to quickly switch back to my chipped P28 if I need to.
Does anyone know where I can get an OBD1 ECU side plug w/pins and a pigtail?
Do I have to chop up an OBD1 ECU to get the plug, and then solder on my own wires?

Thanks
Ben
