That’s what I had thought.. so it being connected to An volt 8, pin Just needs to be moved to a DI pin?

Hey everybody, getting some finishing touches finalized and one thing I was trying to ensure works, was my momentary switch wiring for launch control. I’m using a tweaked engine harness, and it appears to use an volt 8 for the launch control input. I wired in my momentary switch from my launch control switch in my is300; 1 side to ground, other side to the ecm. It’s a normally open switch. whenever I enable the switch, I can see it sitting at .01 v and enabled drops to 0.. not really sure where to go from here.. if I check the active state to low side- it says it’s activated. And high side, says inactive but will not switch when enabled.. any input much appreciated, maybe I’m over complicating something simple. Thanks a bunch!

Got it. I’ll start with that, thank you for the help!

I’m going to attempt to start my motor tomorrow - specifics- it’s a 1jz vvti jzx100 engine, bc264 cams, 1600cc injectors, 1zz COP and some other goodies. I’ve verified all the outputs that the ecm controls(fans and fuel pumps) and all my sensors working, can network is operating, ive entered coil dwell times, injector dead time data. Good fuel pressure, oil pressure, and the remaining inputs verified to be good also so onto my concern, since this basemap I’m modifying uses stock 1jz injector.. I’m running 1600cc and don’t really understand how to safely start the car without dumping fuel into the cylinders.. any help would be much appreciated, thanks in advance!
