Your st165 disappeared a year or two ago. Have you had it that long or was there another owner in between? I didn't make an offer on the car, my friend talked to the guy and gave him my number. The owner left me a voicemail stating he wanted $3k for the car, and he would include a second engine for $2k if I remember right. I though that price was crazy so I never called him back.
As for the connector, there are a few posts that explain what to do if you look around.
