Definitive Green Wire / MSD Connection Thread

[andrew15]

I've done the searches and still have a couple questions -

Background:
I'm getting ready to put 2 MSD 6AL units into my car and will be using a distributor with the magnetic pickup / green wire from the SC

Issue # 1
MSD says the following connections are correct:
Violet wire - Magnetic pickup signal
Green wire - Ground wire from mag pickup

Many people on this board have said that the MSD wiring is in fact reversed and SHOULD be:
Violet wire - ground wire wrapped around green coax cable
Green wire - Green coax wire

They add that hooking it up as per MSD instructions will in fact lead to timing being off and a high rpm miss around 5k rpm.

Any other opinions out there?


Issue # 2
On the green wire connector, which tab is the green coax and which is the ground cable that wraps it? I've included a picture below with numbers is #1 the ground or green coax?

Issue #3 - more reference than anything
In connecting the MSD green / violet wires to the green wire, it's been suggested you can hack into the loom, or use a Bosch fuel injection connector. The new connector route seems the cleanest way and apparently MSD has a pack of 8 connectors for ~ $13. It's PN- 2400 for reference - I'm going out today to see if I can find a pack and if they fit.

Thanks,
Andrew M

Anyone know which tab is which?

Front row left to right
1) System Ground = Black coil wire
2) Tachometer Signal = Black wire from left end of MSD unit
3) Signal Ground (green
wire shield) = Purple wire

Back row left to right
4 Coil Hot +12 volts = Orange coil wire
5) Switched +12 volts = small Red wire
6) Signal Pos. (green
wire center conductor) = Green wire

Thanks Vash - I'm using the MSD harness and a connector to attach to the green wire - Can you shed any light on the above picture - ie which tab is the ground & which is the green coax ?
