Im trying to put in an aftermarket stereo but am unable to find an accurate wiring diagram for the wires that comes from the car. Has anyone been able to locate or know where to find this

The heat went off and lights for heat are off and the shift gear will not move out of park

When in second and third gear or around 20-45 mph it shudders. Can feel it and hear it.

Th3 gears are not going in right I have to exeletate for it to berly move

Shifting high, seems to have a hard time getting above 50mph. Will, but doesn't like it. Gives kind of a whine/groan, RPMs riding about 35-3800 at 45mph, about 4200 at 55mph. Won't take it faster for…
