ECU problem on 90 TEG

[vtec919si]

i just got done rebuliding my ls vtec engine, and i put it back into my 1990 teg, for some reason its running funny when it goes to closed loop, i can't see if a check engine light is on or not, cuz right before i pull the engine out, my fuse box burned, i replaced every sensor and the fuse box and i drove it for a week and it was fine, now i know there is a way to jump a wire from the ecu and pull it from the red light, but WHAT DO I JUMP?? i don't wanna do it wrong and fry my ECU, lil expensive for me right now, espacially at the last step of the build. thank you for ur help

If it is OBD0 you don't need to jump anything.. just turn the key on and it will start flashing the LED in the ECU cover.

thank you norcalgsr u helped again, and i looked into more this morining, and it seems to be fuel or air problem, and my question is, would a throttle body from a b18 work on a b16 motor???
