The afterglow relay, however, doesn't run for three minutes if there is no start attempt. In all probability, blocking the "start" signal would substantially shorten the cycle.
Yes that is true. I did in fact buy the Bosch relay. If there was a choice of relays that operate differently, I did not know it. I purchased the only available relay I could source locally. And when it comes to parts like that I only buy new.

I never timed the relay to see how long it would glow the plugs if I don't start the engine. I know it does take three minutes after start. Would it be hard to block the start signal? Is that a simple disconnect or is there a rewire in order? And would blocking the start signal mean the plugs would be glowing while I'm cranking on the starter? How negatively would that effect my electrical system?

Thanks for the replies!
