Ok so my engine and distributor are a factory set up.ccw is the direction it was designed to run.so being that all the hard parts are the same and wired the same (only diff from a corvette dizzy is...
This is a screen shot so sorry for the small print.I realize this is microsquirt related.just figure the hard parts work the same.same parts numbers.just opposite rotation. 13051

1302813029 the pic is wired same as factory.second pic is wired opposite
After much searching and reading I've found a fair bit of info on this.looking at new large cap hei distributors I see which color wire goes to which pin on the 7 pin icm.my understanding of the...
