Oil pressure switch mercruiser 470 glasply project

[aarons 470]

Looking for a place to run the wire from the “ i “ tab on my oil pressure switch for the electric fuel pump.

Is it ok to use the positive side of coil, or does that rob to much power from ignition?

Will be Using Petronix igniter ignition module with matched coil, if that makes a difference.

If not coil, where should I run the wire for ignition power?

Thanks

If you use the coil power feed to switch a relay, that's fine.

ok, is that what it’s doing in this case,
the “ I “ just flips on the relay? Lol I’m not sure.

I’ve wired it up the way you guys walked me threw awhile back. I have a relay and switch installed.

Someone gave me this picture from a previous post. I’m all wired up except the one wire.
