Losing 6 cylinders after extremely hot weather and/or after a wash??

I wanted to update everybody that I found the culprit, and it was indeed the panel fuse. I started the car from dead cold and it was obviously running one bank only, the motor was hesitating to keep idling and I touched the precats, and while RH (1-6) got warm LH (7-12) was completely cold (checking the exhaust pipes was not a good test because both were releasing the same flow due to the shared muffler)
I started driving and it was obviously that one bank was dead.

So the last and final test was to wiggle the brown cable connected to the Y connector slot P63 while the car was running and VROOOM the bank restarted. It was so obvious the change of idle.
Well now I will bypass both fuel pumps P63 (7-12) that is burnt and P64 (1-6) that is fine just to be safe.

The car has already bypassed both waterfans and the A/C
It is obvious both things were done by different mechanics because the A/C was bypassed with a blade connector and both water fans were bypassed by connecting them directly to the relay.
Which one is a cleaner and more recommendable fix??

I want to help everybody for all your help.
THANK YOU!!

I sent the pictures to my mechanic and he said he will fix all the connectors again, that either connecting directly to the relay or a blade connector is a "a stop gap" fix. so I am sure he will do something similar to what you said.
I just can't understand why 2 different mechanics fixed the A/C and water fans differently and they did not fix the others as a preventive measure.
By the way my mechanic added a 8th connector to your list
1 AC
2,3 Fuel pumps
4,5 Water fans
6 Oil radiator fans
7 AC condenser fan
8 Starter.

 

Thanks Steve
