Hi there! I'm wiring up a fuel pump to bypass COR. I'm using the green wire from B1 connector to send ecu signal (ground) to fuel pump relay. My question is, I turn the key to accessory, ground cuts out an signal goes away. So there goes my ground signal for relay. Is this green wirr supposed to send ground signal again once the engine runs? My car is not running due to lack of parts yet. I have a gray plug ecu and harness from 1992 supra I believe. It cranks over. The car itself is a 1980 sr5 corolla. Pls help me out verify if green wire is supposed to lose signal when key is on IGN or accessory but will shoot out ground once motor is actually running. Thank you have a nice day!
