MSD 6A and Bosch CD box on 911T (1969)

[cdomingos170]

Hi,

I am refurbishing an 911T from 1969 in Portugal and I bought a MSD 6A ingnition and Tach adapter.

After read the instructions and consult several forum threads I have a doubt: Could I take off the old Bosh CD box or the MSD 6A works with it?

My doubt comes from the fact that I wll need to use the actual coil cables to connect to the MSD and then connect other cables from MSD to the coil. So it seems that it use some processes from the old CD box that is in the middle???

Please help!!!

The MSD replaced the Bosch box. You don't use both, you take the Bosch box out completely and put the MSD in it's place.

Please, does someone know where to find an ignition electrical blueprint/scheme?

Are you looking at how to power up your MSD? On my 14/6 the MSD gets it's power for the switched lead that use to plug into the CD box.
