some msd/o2 sensor experience needed

Several things affect what you'll need to run it at but the biggest thing I've noticed is if you have a big lumpy cam you'll have to run it pretty rich to get it to idle decent. I have a fairly mild cam in mine and run the idle as lean as I can to try and get some fuel mileage out of it. Around 13.8~14 to 1 in drive is where I run it. At WOT it runs best right about 12.5 to 1

I noticed the instructions said it will read lean at idle with a lot of overlap ? I have around 260 @.50 overlap and around 535 lift. Right now as i read through the instructions for tomorrow , i noticed I can't hook the power up to anything basically that runs anything else ? One long wire (another one !) Through the firewall to the battery in the back ?
Thank you all again.....
