MSD Routing to 8 Pin Euro Anyone?

[Robbbyg]

Lots of info on howtos on installing MSD ignition which ive followed,
but then car didnt start,
so i changed a couple of wires and it works but no tach go figure,

But im looking for a Correct how to on this,

I want the MSD Box wiring to go directly through the 8 (eight) Pin Harness that was connected to my EX CDI which i sold to pay for my go fast bits if at all possible.

Reason is because the less wiring through engine the better im trying to keep it minimalistic , sort of..

Anyone know of any paper write up on this, has anyone ever done it??

The Euro 8 PIN CDI as far as i know were only made in 76/77 and never avail in the US as far as i know but there have been exceptions here and there, so my chances are slim on this process i know.

Engine is 930 Euro Row 3.0 formerly with 8 pin Bosch CDI ,
Harness is still in bay to connect to see pic edit cant see it in pic but it is in there somewhere

Info needed MSD to Eur 76/77 8 PIN CDI Harness
