Top is original retrofit with RB ignitor and bottom is with Z32 ignitor. See how the 3 pin plug has wires labelled differently?

This also eliminates the small 14 gauge wire to control the coil, rather now this includes how to wire up a relay and using 10 gauge wire directly feeding from battery.
I have a question about this Z32 ignitor application of the buick coil retrofit. In the pic above, it shows the center wire from the 3 pin plug being GROUND and going to the ground on center of injector side of ignitor and going to earth.
On the very first page it shows the center wire from 3 pin plug being called POWER. I tried this before and nothing happened wiring it up as the diagram above and thought i had issues with the relay.
Can someone please clarify this for me? Does the center white wire go to the ground on injector side of ignitor and get grounded, or does the top wire in this diagram marked 12V go to the ground off of injector side of ignitor? I am not very good with wiring but can do this if I know this one detail.
Thank you.
EDIT, I spoke with DriftX and he told me he wrote this a long time ago and did not have the car anymore and to use common sense. He was helpful and I looked at it logically.
The 3 pin wire on the diagram is backwards. The center white wire goes to the relay across the coil side from ground. The black and purple? or black/red wire off 3 prong plug (opposite side from trigger wire which is black with 2 silver rings) (the white wire is in the middle)) The black/purple wire on 3 pin plug goes to ground.
Hopefully this can help others. I am getting good spark on all 6 wires, but I think I have an injector issue to be sorted out, #2 and #4 are not getting fuel. Will this ever end?
********EDIT 2.23.2011: Did compression check last night, avoided it because I was sure I had 2 dead cylinders...Compression was 130 to 140 across, no issues. After rethinking it, I wanted to try another ignitor. My friend was with me with his RB hatch, which inspired me to try to mess with it again...and his has RB ignitor. He also had a spare Z32 ignitor, which we retrieved from his house, plugged it in, laid it on top of my old ignitor and it started and ran fine! Need to adjust CAS now since I have tried everything to get it running.
The buick coils are great! I recommend them to anyone, it will look tidy also as soon as I put the cover on top of plugs/wires...the wires come out of back of cover and run along firewall to the windshield wiper motor area where the coil is temporarily (or permanently) ziptied in place.
I just had to post this, I can now enjoy my RB20! Hopefully my clarification of the wiring posted aboe helps someone, but the real work was done far before I got involved.
