Bosch CDI to MSD 6AL - 2024

[francesconyc]

I'd like to install an MSD 6AL box to replace the Bosch CDI, but i'd like to keep if possible the black plastic connector and buy or DIY build one

I found this thread but the PDF is lost...

I wonder if anyone sells something to easily adapt the MSD to CDI

I read somewhere there is a user Timmy2 that creates those harnesses?

or are there other places to find the wiring and parts to buy etc...

Are you looking for the black 3 or 6-pin CDI connectors? If so, I found some at Kroon wire harness dot com

Yes, your 911SC uses a 6 pin CDI (6 wires). When using an MSD, a seventh wire is needed for a direct connection to 12V (red wire) at the starter motor.

yes I read about it. i guess I can connect to the always hot defogger fuse

You are better off running a 12 gauge wire down to the starter to connect to the big black cable from the battery. That MSD B+ wire is high current.

This is the "adaptor" harness I made to install MSD AL-6 in my Son's
78 SC

Timmy2 (Dennis) rewired my harness to convert my ‘71 from CDI to MSD Streetfire. Great work, excellent communication, reasonable price. I highly recommend him.

+++ what doswald said. I have the Timmy2 connector for MSD in my '70 with 3.0. Just plug and play. Super easy. No wiring diagrams needed. Quality work. Give him a call. He's a good guy.

[francesconyc]

can i contact Timmy2 here with a DM?

[francesconyc]

yesterday i studies and labeled the new unit and it seems I have. A LOT of cables that will stay unused...

[varacoustic]

Why not rebuild your good old robust German Bosch unit instead of the MSD?

[doswald]

Yes, you can contact timmy2 (Dennis) here via pm.
