I forgot about the whole idea of using the Homelink part from the Accord until the other day. I decided to do some homework. The part is the same size and shape as in the civic. I went to the dealership and looked at an Accord. I also went onto college hills honda and they now have the part avaliable as an accessory for the '06 Accord. According to the diagram, the part with the map lights are the same shape and size as well. They also have install directions on College Hills, so I checked the connections. Eariler today I took apart the map light in my civic and it also has two connectors like in the diagram for the homelink part and they appear to match. I can't see why they would not match because the only real difference is a switch for the overhead door lights. The homelink device itself has no connecion to the car or computer other than for power. Think I may go and buy the part and try it out.
