Some of the pins came out of the connector on the harness side, not computer side. The harness side connector’s pin holes are too big I think which caused the pins to not be aligned...

    The horns on my 1987 GT convertible foxbody went out. I replaced the horn pad in the steering wheel in case that was the issue, and can tell it's working.

  14. I have a few questions about my ‘90 fox

    I have a 1990 foxbody that I got handed down to me and it’s been sitting for over 10 years and I need help. I’m going to drain all the fluids out of the car first and my first question is to drain the gas can I just funnel it out or do I have to drop the tank and drain it out that way.
