I've read the older posts on 3-way wiring INSTEON switches and I think I get it but I don't want to mess this up.  I will greatly appreciate your patience as I ask this. Please excuse the not great photos but I thought they helped.  Here is Box A.  It has: 

• Line coming in (2nd from left)
• 1 Single pole switch (left most)
• 3 3-way switches (on the right)

The 3-ways are all wired the same way which I'd hope they would be.  

• The bottom right wire is from the hot pigtail.
• The top right wire (red) traveler wire.
• The bottom left wire (black) traveler wire.
• White goes to white pigtail.

Here is Box B (just one example of one).  The traveler incoming wires go to: 

• red to lower left terminal on switch
• black to upper right terminal on switch
• white common tied to the common going to the light

The bottom right black (load) wire goes to the light.  

So from another thread I read here, I copied this below and I hope have it right for my situation.  This is what I need confirmed or changed. (All 3 of the 3-way switches are the same so it shouldn't matter which one I do as long as I match it to the right Box B.)

So the resulting wiring in Box A looks like this:

• 2477D black wire ties into black wire pigtail
• 2477D white wire ties into white wire pigtail
• 2477D red wire is capped
• Red traveler wire in Box A is capped

And in Box B:

• 2477D black wire tied to traveler black wire
• 2477D red wire tied to black wire going to light fixture
• 2477D white wire tied to white wire going to light fixture
• Red traveler wire coming into Box B is capped

Does this make sense?  Correct?  If not, what changes?  Thanks so much for the help in advance.  I've always gotten great support from this group. 

Well I double checked against this diagram and went ahead it with.  All is well and working with a dual controller scene. 

 

Once you do a few, they become more second nature. Glad you figured it out!
