A modern condenser can be attached to the firewall , or the coil bracket for ground . The pigtail wire on the modern condenser should be connected to the switch side of the coil . The switch side of the coil will have a red wire unless the wiring has been changed to a different color wire than was originally used . Where the condenser mounts is the ground and must be clean and tight or it won't run . This puts the condenser in an easy spot to remove and replace whenever necessary. I have run a modern condenser mounted and connected in this manner for over twelve years . An old model A guy showed me this back in 1960 and it is plenty close to the points and has worked perfectly for me . The condenser will run cooler and last longer . The modern condenser will be easy to remove and replace when mounted in this manner . I've been told that the original condenser must be removed from the distributor when this setup is used . I use the modern condenser that is offered with the V8 points setup . The last condenser that was used with V8 Fords can usually be found locally . The condenser doesn't know the difference between 6 or 12 volts because I have used them both ways . This is about as simple as it can get and can easily be reversed .
