Switched power source for fuel pump install

cudajames said

@Mattax that is very interesting, if I understand what you are saying, instead of tapping into the switched power, I connect to the alternator instead? I prefer, that route. And it seems that would still be a constant source of "keyed" power. I see other benefits as well, with out tapping into old wiring

You are confused.

The alternator output is not switched. It is constant. That feeds to the relay contacts

You still need a switched source to key the relay. Re-read what I posted. There is only once source from the key. It goes several places. Any one of those sources can key the relay as they are just branches of the original---from the key
