Power window relay

1986 911 Cabriolet.
It seems that my electrical circuits differ from the Bentley diagrams. I'm guessing this is common.
Anyways, I have been working on getting everything working again. Wrapping up repairs on the fresh air blowers, finished repairs on the heater system and fixed issues with the wiper lever.
Now I am tackling the power windows and the washer system.
I have been having a problem with a draw on the battery when the ignition is off. While checking out the (behind the gauges) relays, I found that one of the relays is hot to the touch all the time, even with the ignition off. It clicks when I turn on the ignition. Bentley says it is the power window relay. Opened it up to find a large resistor near that area where it is hot. I'm thinking this may be the problem with the battery draw. I pulled the relay and my windows still work, and they have always worked with the ignition off. Is this right?
I'll get to the washer system gremlins later.
