[Yellowbird RS]

After reading several posts, and consulting the "101 Projects", everything was clear. But as soon as I see my old car wiring, it all seems so different and difficult. I need step by step instructions to connect the MSD 6AL in my car.
a) My old Bosch CDS has a three pin connector (white, red, white).
b) My coil has a strange connector, from which two cables come out: onee is brown and goes to the "earth" that holds the coil base. Another one is yellow, and joins in a point with a white cable which apparently comes from the MSD. A blue-red cable that comes from the distributer, and all of them get finally together in a black cable connected to the same coil base (earth).
Please I need advice step by step.
