help with wiring, I have dual intank walbro pumps. first pump is wired to factory harness along with hotwire kit and msd boost a pump. for the second pump i purchased painless wiring fuel pump relay, which is activated via boost pressure switch. 2nd pump also has boost a pump. should I add second hot wire kit to 2nd pump also or can I run the painless wiring relay direct to alternator? Also I upgraded to a better hobbs switch, how many devices can 1 switch support. I want my 2nd pump, both msd boost a pumps and meth to be activated on 1 hobbs, is this a safe setup? my wiring is terrible

Use the Hobbs sw to trigger relays for the other, hi load functions.
