like i said in the original posting, you remove the #19 wiper relay and install the #99 one in its place.

I received one of the "99" programmable intermittent wiper relays 
from Chris Turner. (Thanks!) 
 
I looked up the relay in the Bentley manual, where it's described as 
"optional." So let me ask: When I drop the fuse panel in my '84 
Westy, should I expect the socket for this relay to be empty? Or do 
I need to remove an existing relay and replace it with this one? 
 
I spent a few minutes staring at the wiring diagram, too. I can read 
schematics, but Bentley uses a very different symbology that I 
haven't absorbed yet. It depicts the "99" relay using a symbol 
defined as a "solid-state relay" or something. Does the wiring 
diagram label each pin of the relay in some way? 
 
I'm looking forward to plugging in the new relay. Perhaps you all 
can fill in some of the details.
