Does anyone know which wire is + and - for the CYL & CRANK?
The wiring diagrams I have don't really tell me. See below.
A friend of mine seems to think it is the following

Sensor terminal - see below for reference.
B -
F +
C -
D +
G -
H +




The second question I have is does anyone know what the black wire is in the engine harness D/S tower plug? (14pin plug)
All the info I have shows the fan switch, speed sensor & Vtec pressure switch going to ground near the thermostat but there is only two physical wires I can see grounded. I am tipping it's one of them but which one?
