ok , when i installed my headers i broke off my oil pressure sensor

so i drove it a while with it broken off inside, today i took to a shop and had them to get it out and replace it

my question is, i broke off the connector for the oil pressure sensor by driving it around

they said that im going to have to go the the chevrolet garage and get the 3 wires so they can reconnect the oil pressure sensor

whats the part number and anyone know this is correct

its a 93 w/ the sensor above the oil filter , thanks
