Which MSD box do you have? I have a 6AL and it has a built in rev limiter, to change RPM settings in it you change the rev chip in the side.

We use this setup on a SB Chevrolet in our modified. The instructions show the proper connections. One wire to 12volt, one to ground, and one to the TACH terminal on the distributor cap. The rest of the wires are tied up out of the way. Locate the box where it is handy, so that you don't have to take any panels off to change the chip. Good luck racin'.

ok now im lost what setup are you refering to? and all of my ignition is contained inside the distributor and really don't want to change to an external ignition box other than just an add on rev limiter.

I would email MSD and tell them what you are wantin and I am sure they could give you many options!

The setup we use is a GM HEI distributor with a MSD module. The rev limiter is from MSD. It is a separate unit about two inches square and just wires in. I suppose you could use it with a stock module. It just connects to the TACH connection in the distributor, and 12volts from the ignition switch and ground. To regulate the rpms, just choose one of the chips and plug it into the limiter unit. It doesn't stop the motor,it is a 'soft limiter' in that it cuts out cylinders randomly, first one then more to keep from exceeding the chosen limit. We have run the same pieces for years without problems. If I can do it, so can you. Good luck racin'.

Crank and rods always worked fine for us! Of course it's a little more expensive!

ty guys as it turns out the module i have is not a cd module even though that's how it was advertised when i bought it. so the msd soft touch for non cd ignitions will work just fine.
