Fuel pump relay signal wire?

[Slade88]

Hey everyone I’m trying to rig up the wire that will keep the fuel pump on with a wire that’s hot when the key is turned on. There are a couple wires coming out of the fuel pump relay and I was curious if I could use one of those and connect it to a wire that goes to the now removed tbi, is this possible?
