3VZE Knock Sensor Earth Wire question pls???
Some advice please.
I’m swapping a 1990 3VZE into my BHG 1993 but the connector/wiring for the 2 knock sensors are different. I have read a thousand post/ articles about this but still cant work out why the 93 has a black (active to ECU) and a brown (earth?) wire and the 90 has a black (active to ECU) but the puzzle is the shielding wire (also starts out as a black wire!) that surrounds the black active wire and seems to connect up into the loom with other shielding/earth wires.
My question please = Can anyone confirm that I should connect the black wires together and then separately the brown with the shielding/earth wires? Toyota say that all 3vze knock sensors are the same so will this work?
Many thanks. Mitch
