so my 89t jus got another 7mgte put into it but after it the swap was done, when the car is turned on the headlights turn on without the being switch on and flipped up. so in order for me to turn it off i have to pop the fuse box and take the relay fuse out. what could this be?? the engine did come from a 87t and so did the harness and ecu if that helps. let me knoo, any help would be great

What year engine harness was put in? Yellow or gray plug and what color is the harness side?
