Tremec 3650 wiring ???

[Born To Run]

On the trans there are 2 connections one speed sensor & one for reverse lights,which one is which??
Does the reverse light sensor work by just grounding to activate rear back up lights?
Also how does the speed sensor work,ie ground 12 volts etc.
It seems my current setup each pigtail shares one common wire?
Need lots of info to convert this wiring back properly.

this may help: http://www.mgsv-club.com/images/pdfs/TR-3650_Service_Manual.pdf

I searched for speed sensor once the pdf was opened. I'll grab my service manual and see what it says...
