I installed an ignition relay last week. Its pretty easy really, basically you are using the power from the ignition switch (white wire) to turn on the relay and let power from the battery flow to the fuse box and the starter and coil. The advantage of this is that all that power no longer flows through the ignition switch.
The process is pretty straightforward. Incidentally, later model cars came with an ignition relay. My car had had it removed at some point! But adding a relay to an older car makes sense to.

Don't most relays have small frail conductors and springs in them? I thought they were not the best for high vibration environments... especially if the relay is conducting all the current for your ignition. That's why everyone has gone to solid state switches for ignition cut-off.

Relays do go bad from time to time, but I think in this application they are pretty long lived. They are also dirt cheap and very easy to swap out. Literally a couple of bucks and a couple of minutes to change one. So its really not worth switching to a solid state ignition on these cars.
Thanks for your comment.
