Hello All,
I'm looking for the 3 pin female water resistant connector that plugs into the fitting on the driver's side of the A518 automatic. This is sometimes called the Lock-up connector and not to be confused with the round black connector for the reverse / park switch. I have already purchased the Standard Motor Products connector STA S-577 and although it 'looks' correct it does NOT fit. The pin spacing is 3.5mm whereas the transmission pin spacing is 4mm. According to my research the connector 'appears' to be GM p/n 12085538. I'm hesitant to force the connector onto the pins. Hopefully someone has some insight.

Looking forward to the feedback.
