930 MSD 6AL Wiring Help Needed !

[rboylan]

Here's what I know(I think):

Thick Red - Battery
Thick Black - Chasis
Small Red - Ignition
Orange - Positive on Coil
Small Black - Negative on Coil

Here's what I need to know:

White Wire - ?
Violet or Green Wires - ?

Tach Wiring ? - Can I connect 930 blk/prpl directly to tach output on MSD 6AL ?

Do I need to touch the original CDI Harness ?

I am also installing the MSD High Vibration Blaster Coil. What rev limiter should be applied, this is primarily a street car with occasional Track use.

Any considerations, please reply. Thank you.

You should get the MSD installation instruction sheet; they must have a website. If not, I'll see if I can find mine for you. The violet and green wires go to the distributor.

I don't remember this off the top of my head, but there is a wiring chart/guide for the MSD install in "101 Projects for Your Porsche 911."

MSD have good instruction sheets at their site - www.msdignition.com - go to the instruction manuals. Mind you, this is the same as the instructions that come with the unit.

I don't know how the 930 sends its trigger to the distributor, but believe it is magnetic and so you are likely to need to hook it into the magnetic input (violet/green) on the MSD (not the white wire, the pair of wires at the other end).

I put the 7000rpm limiter in my 69T with E cams, as if it is going to make up for the non-counterbalanced crank and lack of forged everything

Try plugging the tach wire into the MSD tach output - I have been told it works on cars of your age (it doesn't on mine though).

THe original CD harness has outputs which more or less mirror the inputs to the MSD unit - the appropriate trigger wires are there. Unfortunately I don't know which they are...

jcrewsn recently did this upgrade to his 930... http://www.pelicanparts.com/ultimate/Forum3/HTML/012812.html

He had problems but they were related to the alternator and AAR (but seemed to coincide with the MSD install).

I'm not sure which year your 930 is, but I'm getting ready to put a 6al in our 86. What I found is that the violet and green wires from the msd go to the dist. the white wire is not used. The correct rev limiter is 6800 and is a special order from MSD. I have the 8920 tach adapter but not sure if I need it yet. I believe that the tach wire is black with a violet stripe. hope this helps lets us know your results... Pat

Thanks for all the replies.

Wayne,

I knew I bought that book fr=or a reason, right there on page 74, the details are reviewed. I'll post the results. Mine's a 79, should be the same as the 86.
