Wiring Question

[N20neenee]

Guys
Im putting my Wisconsin trooper car back together and has a few questions on the proper running of a few pieces:

1) O2 sensor wiring--basically from where it connects at the front of the car and runs towards the back. Does anyone have any pictures of how it should be? I realize the low oil sensor wiring runs off the same connection

2) The speedo cable. My putting my Vas-Car cable in and noticed it has a faster bracket--where does this bolt to?

thanks
Sean

I have narrowed my re-assembly questions to this: Where is the correct place that the engine ground wire attaches to the engine? Any pictures would be great
