Hello all,

2004 GS 300. I was working on my VC gaskets when I was trying to get some room by lifting the wiring harness out of the way, when I managed to rip out two wires from this electrical connector. Below is a picture of said connector.

I am trying to find out what exactly the connector is (on the engine harness side). Anyone have an idea? I think it is one of the heated oxygen sensor wires (bank 2 sensor 1) but I am not sure.

Thanks in advance!

Can you get a close up of the connector from the end so I can see the shape and pin configuration? Thanks.

I was able to determine that it is the connector

for the bank 2 sensor 1 oxygen sensor. Here is a picture. Does this help?

the 4 wire colors are:

yellow, brown, white, black with red tracer

as you can see brown and white are disconnected so I don’t know which one goes to which pin. I ordered the replacement connector, so it would be very helpful if someone could tell me the PIN numbers and corresponding wire colors.

This should help. But know that I am referencing a 2000 GS300, GS400 Electrical Wiring Diagram. I do expect it to be wired the same. Just not the same type of connector. Good luck.

Do you have access to wires on the other conector?? If you do, just cut both conectors off and splice the wires together..

thanks so much Paul this is exactly what I was looking for! Much appreciated!

might just do this if I have too much trouble rebuilding the connector. Just wanted to attempt keeping it neat before I went that route. Thanks!

😡 Don't even think about it.

BUT, "if you have to" in case of an emergency, use a 22 gauge T-Tap wire splice until you can get it repaired correctly. Do NOT cut your harness. Take it from someone who has been working in electrical/electronics for longer than you have probably been alive.

noted! Thank you for the wire spec!! Good to know of an alternative
