According to their instructions for a diesel, yes.
Does that thing actually pierce the wire or is inductive?
Biggest problem with vague instructions like that, chase your butt for hours hoping it's a hook up problem vs issue with the unit itself.
Fingers crossed for you.
thanks, inductive - or supposed to be!
Well no luck. Did not work on red wire or green wire on coil (then stripped them a bit to ensure contact, still no). Tried injector, nope, rechecked wiring and installed 22hm resistor on green, nope and nope.
Well unless someone else has an idea i am spent. Will have to wait until I put an msd box in.
wonder if you need a tach adaptor?

I'd call MSD for their take on things. According to application chart, is suppose to be compatible with your car.
So, usually in business or life when you are trying to figure something out logic and what appears to be wrong usually is , then deduct from there to solve the problem.
To start then with what I know and tested:
Tested the power to the coil. 12v+ . - all good.
Tested from the GMR to the shift light, no signal (less than 1v) on all lines. MSD states the green line should have about 5v.
Tested the GMR , without power but with a tester, zero runs from one end to the other.
Tested my 12v source that powered the shift light, all good - and that makes sense as the light starts up, cycles through the programs etc.
From my view then the GMR is fubar. I am ordering another one and will see if that works! Will update on progress.
Nope according to MSD the digital shift light and GMR are all i need!Originally Posted by tulowd
I don't really know what I'm talking about so please be patient... Do you really need the GMR for an 87 5.0L? Can you cut it out of the loop?
