95 G20 Speed Sensor Bypass Wire Help Please!
 

I have a 95 Chevy g20 van. We have the 4l60e transmission. And to get the transmission to work we had to get a sensor bypass done. The van ran great! But now the wire for the bypass got unplugged and can't figure out where it goes. Nor can we get a hold of the place that did it. Without that wire being attached some where the transmission won't engage. If anyone know anything about it please let me know thank you!

Are there any more details on the invoice, such as which sensor? When you say won't engage, I assume you mean it doesn't shift into drive and reverse?
The only thing I can think of is the brake pedal switch, since you need to apply the brakes to shift, right.
