re: 387f. E series ISO can have waterpump running even with the car off. There is a power wire bypass fix that I did that fixed this. Before the fix, I could hear a hum from underneath the car with the car off for several hours. Never drained the battery badly unless it was winter but the voltage was really low. Alternatively, some have wired their JB4 to a constant 12V on source by mistake.

re: 3166. So I unplugged connected the stock MAP connector back with nothing connected to the JB4 MAP connectors. Update: --> 28A0 and the usual 2C90
