I was trying to fix my taillights and brake lights on my 1974 ford maverick by changing some fuses and ended up jumbling some wires under the dash. I pulled out the yellow box (ecu?)to see the wires behind it, and this plug (?) fell out. it has a black/pink wire and a white wire. when I tried to start the car after, it wouldn’t even crank. it started right up every time before. I am almost 17 and have no training or teacher. if anyone knows about this wire it would be a great help! I never finished changing out the fuses, but I don’t think it would be a fuse problem since all the fuses that were there before are still there. is it because I pulled on the fuse box? the radio light still comes on, but not the red one on the instrument cluster. I’m hopeless when it comes to the electrical side of things♀️
