Switched 12V source for external fuel pump

I am looking for recommendations for where to wire in for an inline external fuel pump for going FI on my 69 Camaro. Any suggestions would be appreciated.

Use a relay. Supply the coil with a line from the IGN terminal on your fuse block and supply the contacts with a line from the + post on your battery.

As Steiner suggests, use a relay. I suggest you use a 3rd Gen fuel relay and fuse accordingly, the supply line from the battery or power junction block.

Your decision, but you might use an oil light sending unit in the relay coil circuit to open up when oil pressure drops.

I would also look into a hidden switch for the relay so if you leave your car somewhere (out front of a friends house or something) you can turn the switch off so IF someone was to TRY to steal.... they'd get nowhere if they were to hot-wire

Your ECU should have a fuel pump control circuit built in??
