run stand

will this set-up work like this . the ECU mounted on the engine block with the ground from the battery. the "E" representing the engine. the blue wires representing the wiring to the push button starter. can i tie the "start" and "run" wires together and connect them to the positive side of the battery. im asking because this is what i have to work with outside of putting this in the car. i have manual oil and temp gauges along with a push button starter

again i apologize for the thread jack, i should have just started my own

sorry for the ghetto drawing LOL
