[Elecraft] W2 Integration Question

[Leon Begin]

Need some help to un-confuse me. My current configuration is as follows:
K3(&P3)-W2-KAT500. I¹m days away from ordering my last upgrade, a KPA500 &
the Aux Cable set. I know that the W2 may not be a necessity now with the
KPA500 built-in watt meter but I bought it, assembled it and it does balance
out the appearance of my K-Line. The current cabling diagrams on any of the
above components do not show the W2 in the loop. Anyone out there have a W2
in the K3-KPA500-KAT500 configuration and what is the correct cabling for
it? BTW, I¹m going to miss all those 2D fastener¹s and itty bitty washers!

Thanks,

Lee
