Heater and engine check light on after ecu swap

I did the ecu pin swaps of pins 20 to 32, 21 to 34, 6 to 53, cut pin 87 and ran a wire from pin 79 to allow me to flash the ecu and it worked, the car starts and i am able to read a nd write to the ecu. I only have one issue, when it runs for like 1 min the heater and engine check light comes on and remains on. The pin i use for the flashing was pin 77. i Clipped pin 77 and ground it onto pin 92 and use the other part in the ecu plug for pin 79. Is there anything i did wrong here or what i left out? As i said before the reading and writing to the e7 ecu is fine is just that i am getting the engine and heater lights on the dash board.

This is what i have been following:
