So i was installing my shift light and misread what wire to install the yellow wire to. I hooked it up to the ignition pulse wire #1 on the ecu harness. My car still starts but doesn't wanna idle. Did i short something? Where would i start to fix this problem.

Its for a 04 tsx with 07-08 tsx ecu and flashpro

If you damaged the ECU you will need to return the ECU to stock and unlock the FlashPro from it before replacing the ECU.

Is there a way to see if i shorted out the ecu?

Based on what you have said, you damaged it by miss-wiring something.

I tried a new ecu and same results. So im guessing i didnt short the other ecu. I checked my fuses and everything looks good. I soldered that ylw/grn ignition coil pulse wire to have a better connection. Tried a new coil and nothing. Im thinking main relay

I would recommend you remove what you have installed and see if the problem goes away.

I removed the shift light and still not working. Tried changing
the ignition coil relay, main relays. Changed coils packs as well. Checked if i was getting power at coil plug and injectors and that checks out good as well. Was gonna try cam and crank sensors. Dont know what else to check
