Hello, I have a 2003 F350 that this kid swapped a 12v cummins into. When I got to looking around the wiring was a huge mess. The kid only used green wire for everything! Anyway It took me 6 hours to get the wires untangled and fixed for the most part. I had a few questions though.

1. On the end of the brake master cylinder there is a plug with 2 unhooked wires. Can someone clue me in on what these are for and what color wires they are supposed to be.

2. I can't seem to locate the wires for the clutch on the ac compressor. If someone could tell me what the connector looks like and what color the wires are.

3. I can't get the speedometer to work I have checked the ground on the abs and replaced the sensor in the rear end I cant seem to find any broken wires.

Thanks in advance.
