Re the delay relay. You can simply repatch the connectors around it and leave it there. It was a retrofit add on in 77. It was to allow the dash vent door to open by vacuum before the Hi blower blast fought the door when going from OFF to MAX AC. The simple fix is to go to NORM AC first using a lower fan speed then move it to MAX. I never use OFF position and leave mine in VENT as a default. I want fresh air coming in whenever coach is running. This works driving on cool mornings where you can warm the air as needed, then go to cold outside air as sun warms and then just move lever to NORM AC as the greenhouse heats up. You will get slightly less voltage drop by eliminating the delay as every connection and added wire drops it a tenth or so. It adds up
