Mine is not, just noticed it. The instructions say to cut it in the front of the book. Must have overlooked this, step.

I read that the green loop provides a timing compensation for different style trigger pick ups.

Now I wonder if this is the reason my car didnt pick up much power after the 1st intial timing adjustment during my tune????

You are only supposed to cut the green loop if you are not using a EFI Ford distributor. That is the answer i got directly from MSD tech line when i put my Digital 6 in my car 5 years ago.

So if your car is EFI with either the stock TFI dizzy or the MSD replacement TFI dizzy leave the loop connected.

I ran mine off a realy / the clutch / a momentarty switch.

basicly you hold the clutch in and the momentary switch at the same time. let go of the push button momentary and the clutch holds the 2 step on.. once clutch is out it turns off until you hit the BOTH clutch and the button again..
I have the wiring diagram somewhere if you like. it make it much nicer.

is yours a digital 6?? if so is the green loop cut??


I swear mine was CUT for almost 2 years.. The box was out for a while and the wire was cut but when I went to put it back in the car I guess I was trying to send smoke signals to Chicago..lol

I miss the 2 step allready but on a good note with JUST a MSD coil, I can still run 12psi without spark blowout lol



the MSD book says cut the wire, call MSD they say leave it, call summit racing tech and get even more confused lol...

Then they need to update the instructions. I ran it for years cut, per the instructions. Had no issues with it either.

Magnetic Pickup Compensation
Note: If your application uses the MSD's White wire for the trigger input, the magnetic compensation circuit is not used.
The Green wire loop of the MSD provides a timing compensation for different style trigger pickups. Having the ability to program for the style pickup being used provides a more accurate timing signal. This compensation is used primarily with crank trigger or locked out timing applications.
The Digital MSD is programmed at the factory for use with an MSD Crank Trigger or GM magnetic pickup. If you are using an MSD Billet Distributor or the magnetic pickup of a Ford or Chrysler distributor the Green Loop should be cut and sealed (Figure 3).
Note: It is recommended to check your total timing to ensure the setting for your application.

THANK YOU VERY MUCH !!!!

I had mine hooked up like that for a long time with NO issues. I got used from a guy running a turbo mustang and the wire was cut. I read the instructions and it said cut, so I left it cut.. ran great until I tried to catch it on fire lol

The question of the day is, how much if any does this affect timing??? May need to go to MSD forums to find out.

They dont need to update the instructions. A TFI dizzy is NOT a magnetic pickup.

Read all the instructions, not just what I posted above.

Another part on Page 4:
Quote:
This wire loops out of the strain relief. It is used to compensate for different magnetic pickups. The MSD is set up to be used with GM distributor and MSD crank triggers. If you are installing the ignition with an MSD Distributor or Ford Distributor, this Loop should be cut and sealed
That plainly says just "Ford Distributor". Doesn't say anything about TFI vs magnetic.

Or the reference to "Figure 3" diagram in the post I did above this one, where the diagram says "Factory Ford".

Looks like they need to clean up the instructions.

Blue = This wire activates the Two Step Rev Control. When 12 volts is applied to this wire, the low rpm limit is activated. When 12 volts is removed, the rev limit returns to the high limit.

Pink= This wire activates the retard stage when it is applied to 12 volts. When 12 volts is removed the retard is deactivated.
