thanks all.
I was trying to avoid yet another relay. As reliable as they are, it's just an added headache if I have problems in the future. I guess one 50A relay coming off the Blue wire to run the entire 'Switched' Panel of toggle switches wouldn't be that bad.



Depends, are the switches turning on RELAYS or the LOADS directly? If the switches are merely turning on relays, there's no need to use a relay to feed the switches.

Frankly, the BEST way to feed a buss for all big loads, fans, stereo, etc, is probably to get a "continuous duty solenoid" and turn it on off the ignition, then feed everything else off that.

The problem with adding stuff on these cars is several:

The ignition switch and connector has it's limits

The bulkhead connector is a problem

The wiring is not large enough
