I have a 87 Toyota Pickup 22R-E and i need to replace the O2 sensor. I went to the parts store and bought a new one. The old connector runs 4 wires and the new connection only has one wire and the wire harnesses don't match up.. what do i do? can i just splice the new wire into one of the existing wires?
