Howdy all
i have a m54 swapped e30 convertible, I hooked everything up and the ecu needed power on pin 7 of the X60001 connector. I took the power for the heater of the down stream o2 sensor and ran it to said pin (both are 12v 30a). Everything read fine and I could see codes and identify the ecu after. Once I went to clear codes, I lost connection to the ecu and went to test power, everything that once had ignition power no longer has voltage. As far as I could tell everything has continuity power and ground sides respectively. All fuses in the box and the 5 main fuses for the ms43 is all good, all relays are fine as well, what would be missing for me to not have ignition power anywhere in the car. Only thing that works is the dash lights. All ecu wiring has 0v
