Hi Mark
In your photo above labeled Left Bottom.jpg It seems you have 2 wires exiting the collector of Q12. The wiring on all the PL400 harnesses I possess have only ONE wire exiting the collector of Q12 and that wire goes to pin 6 of each channel (photo below of original PL400 harness). What is the second wire and where is it going to? Red wire goes to Pin3, Yellow wire goes to Pin4 and Gray wire goes to Pin6.
