Need help finding a wiring diagram

[JustFixIt]

Im tring to figure out my friends 1993 Corolla DX 1.8L auto. They had a codes 42 for the VSS so they replaced it. Now there's a code 42 and code 52 for the knock sensor. The engine runs excellent so I dont think the knock sensor is picking anything up. It does have some shifting issues when you first take off but its fine then. I believe its in the wiring. Does anyone have a wiring diagram with the VSS and knock sensor on it. Every diagram i've found at the autoparts stores dont even show the VSS or knock sensor.

Any help would be greatly appreciated!

Thanks

VSS is on the instrument cluster diagram. red/green and red/yellow

Cant find the knock sensor in the diagrams either!
