i know me and me dad use to but this set up on our older trucks and i think we had to hook up on to the switch side of the (sil) and on to the coil. but the coil hat to changed to a electronic one. and it worked fine, i just use the old points on the older models i know the points up buy now are the cheap ones but you can still get the old good sets for under 20.00 made by borg warner and accel still have the ones made with the fiber board not the plastic. so i use the old style and i get about 6 to 10,000 miles out of them before replacing
