Bp automotive wiring harness installed on LS swap squarebody Chevy part 1

Installing my BP automotive wiring harness. On my LM7 5.3 LS. For wiring harness with O2 sensors, the PCM mass airflow sensor and the 4L80e connector.  everything worked out perfect with the harness.

I'm doing a similar build on my channel. Just fired my truck up.
