"ok do I leave the green wire atached to the tach input on the msd and hook up the white wire to it as well?"
What are you talking about!????!!!???
Read the instructions again...
2. Plug the <u>MSD White Wire</u> into the <u>Harness Coil Connector Green wire port.</u>
This is the 'Negative' (-) side of the <u>Coil Connector</u>,
and may also have 'Tach' molded into the connector.
At NO point does it tell you to plug anything into the MSD Tach port...
This is a good way to kill the module!
Take the MSD White wire, and connect it to the Factory Harness Ignition Coil Connector Green Wire Port.
Take the Small MSD Red wire and connect it to the Factory Harness Ignition Coil Connector Red wire port.
Unplug the MSD from the distributor, and plug the FACTORY HARNESS INTO THE DISTRIBUTOR.
The MSD mag trigger (purple and green) WILL NOT BE USED.
MSD Cable #8869 Will NOT be used at this time.

"I under stand that I use only the white wire not the green and violet from the mag pick up. If I knew this sooner I wouldn't have bought the msd 8869 but I guess you learn as you go."
It's not wasted. You can sell it to someone that isn't using a BBD, or you can save it for a day when YOU aren't using a BBD...
If this is the ONLY money you spend on stuff you don't use or doesn't work, consider yourself blessed! I've got a couple of garage bays full of stuff that didn't work, didn't fit,
turned out to be junk, or was just plain stupid!
"One more question I bought the springs for the distributor do I have to pull the distributor to install them if so is it worth all the work?"
You don't have to pull the distributor to install the springs, it's just much easier for someone that is experienced with doing this sort of thing.
Unloading a Motorcraft distributor from the top can be hard on your back bending over the engine, and it can be hard on parts. Lots of parts get lost easily when you are doing something like this.
It's easier to crank the engine over to #1, locate the mark on the balancer on the timing tab, flip the cap and plug wires, and pull the distributor.
You can take the distributor inside and work on it at a work bench then...
I'm getting ready to do another Motorcraft distributor for a friend, so I'll post the steps on my web site while I'm doing it.
That should help some people... Please keep in mind, it's a lot easier for me to build an ignition system from scratch than to make a web site with pictures! (86 thumbs tied in a knot...)
So give me a little time and I'll post it.
