Toyota connector part numbers 👨‍🏫

Did you know that moulded into the back of most Toyota connectors there is often a 5 digit part number which makes up the second half of the Toyota part number.

The first half of that part number begins with 90980- (Note: some newer vehicle connectors have a different prefix)

In this case this Toyota Knock sensor connector is 90980-11166

You can also find these Toyota part numbers on connectors used in other brands of vehicles which still match up to a Toyota part number.

This 2 wire idle control valve works with most aftermarket standalone ECUs and involves no coolant whatsoever!

We also sell a plugin harness for the original 2 port ICV wiring which means this will work for lots of patch harness users. The original ICV must be wired to a ECU output.
