Bear in mind there ARE SOME ENGINES which you do not want to wire up "one wire off' and try to run it. Comes to mind the GM V6's. There is "even fire" and there is "odd fire" and some of them had distributor caps where the spacing between wire towers was NOT symmetrical, that is they were "paired" with two close together and two further apart, and the points or pickup trigger was built the same way.

I believe there were some 4's built that way but I cannot think of an example
