OK, Try this...



The 'Ignition' wire from your 'Painless' kit should connect to the small red wire as shown...

*IF* you don't get ignition when cranking,
And it's possible depending on the swich you have,
Add a wire between the small Red & the 'I' terminal on the starter relay...
That will power the MSD module while you are cranking.

Not all vehicles need it, just see if your harness is going to power the 'Ignition' wire when the key switch is in the 'Crank' position...
If it does, you won't need the extra wire.
If it DOES NOT, you will have to add the wire.

DON'T BE CHEAP!
BUY the MSD adaptor p/n 8869,

http://store.summitracing.com/partde...5&autoview=sku

It makes the distributor a 'Plug In' to the MSD hardware, and it keeps the magnetic trigger polarity correct for the module.

If you are really tight and don't want to spend the extra money, take a CLOSE LOOK at the wire color coding between the module and distributor.
The diagram IS CORRECT... And 90% of the people who splice get it wrong!

And buy a new coil connector for the coil you are using from NAPA or somewhere.
The part numbers are listed on the diagram.
This will make your install a 'Snap' and make it look so much neater...

If you need more cable to reach between the MSD and the distributor adapter, try MSD p/n 8862 for 6' of extra reach.

http://store.summitracing.com/partde...5&autoview=sku

KEEP THIS WIRE AWAY FROM SPARK PLUG OR COIL WIRES!
If you let it get too close to high energy wires, you will get false triggers!
Notice MSD put the trigger wires on the other end away from everything else... There is a reason for that!

WOW!! thanks that is everything I could ask for And is how I have my stuff setup. I am using a new msd tfi blaster coil. I think my problem is I am grounding the msd box to the body not the neg on the battery. I will try the I term If I am still not getting ingtion. thanks.. one other thing I looked over was cutiing the little red wire inside the msd box to set it up for a inline six.

Thanks again
Trey
