Hi all, I am working on a bosch ignition module from VN/VR V8 Commodore (not 100% sure what its from) . Has been tested in a car and found intermittently faulty. So thought id give it a go fixing it . As in picture colours left to right

Also
I have taken board out and resoldered some dry joints

1) black 2) light blue 3) grey/red 4) red 5) white/black 6) brown

1)black to neg
2)hall effect sig in
3) grey/red 12v+ to hall sensor*****
4) red power 12V+
5) neg to hall sensor *****
6)brown neg coil

First problem / pin 3 and pin 5 one has red trace other has black trace . U would think pretty straight forward 12v+ and neg . when I power up ignition module the polarity out of (3) and ( 5) is reversed to the dizzy hall sensor.
I have tried it with the dizzy with and without correct polarity but no good.

Looking at the VT wiring here viewtopic.php?f=32&t=2265#p21753
Grey/Red looks like ground and White/black looks like positive.

This is the wiring I have been following. As mine is not Vt with cam sync . The VN V8 colours seem to match up better except for the PINK instead of RED going into module.

My point (looking at both diagrams) is why would you use a wire with a black trace for POSITVE and a red trace wire for NEGATIVE?

I do not have the harness plug that goes to the dizzy , if anyone can test the plug to find witch pins are what would help with this part .
