MSD BTM?

I have an 89 gt and just installed a supercharger and just took off the msd 6a box it had.I have the btm installed but dont know where to put the white wire coming from the msd btm unit,for breaker points/electronic ignition?.I assume it goes to a wire from the plug in my distributor but dont know what 1,any help appreciated.I dont have the original harness it was hard wired into my msd tfi coil with the orange/black wire.

Check Msd's website they have all the diagram's available there.

I am aware of the website and have looked already,shows it plugged into a harness that is no longer there.I need to know what wire it goes to.

On my 6BTM box I hooked it up the same way the 6AL was that I removed. No extra wires. Just the plug in for the knob in the car.
