Hi everyone I'm new to all this stuff. I just finished up putting an Lq4/4l80e in a 1986 GMC 3500 3+3 dually. I used the PSI wire harness. I'm not sure what my pcm is called or witch number I need to know how to identify it. I made a bench harness and got the Obdx pro VT. Then I followed the new video from randy at low buck ls on universal patcher to turn off vats and rear O2 sensors. The engine and trans is all rebuilt and I added a BTR truck norris cam.
Here's a picture of my pcm if anyone can help tell me what number is important to identify it. Amd here's the truck pulling home the donor truck
