Fuel Pump Wiring? PCM and Ignition or Just PCM?

Caution... rookie builder fuel pump question...

69 Charger with 6.4 Hemi Crate Motor using Tanks Inc. tank and fuel pump assy...

Do you need to hook up the fuel pump relay wire to the PCM and to ignition or just to the PCM fuel pump wire?

Thanks!

You can do either way. The harness pump wire will be the trigger wire if you use a relay. Or if the pump doesn’t draw a lot of amps, then it could go straight to the pump.

Thanks! I bought the tank and pump from TANKS INC. - they recommend using a relay so I assume the pump draws a fair amount of current/amps.
