Also note for general knowledge that Pertronics does not make a III unit with multi spark and rev limiter for our electronic distributors.
If you have electronic now and want to run thier new module you will either have to do it with a points distributor or mod your electronic somehow to accept it.
It also cannot be mounted external like the older 4 pin type we have seen before, as it has to be near the distributor points cam to sense off of. (one of the things I don't like)
The 4 pin GM style with rev limit can be used external of the distributor because it does not have the pickup sensor built into it.
Also as far as I have seen they don't make an HEI III 8 pin module with multi spark and rev limit. (I would like to have those as an option for our HEI kits)
I have been trying to find a way to build our HEI kits with multi spark AND a digital rev limiter, but either someone doesn't make a part yet or it doesn't exist at all.
