Yes, I've got an 85 touring wagon. My understanding is that there are some significant differences between the pre- and post-85 300 models, I don't know if this would include wiring as well.

the R & L rear panels would make sense, thanks for the tip. I do have an electronic manual which I will look into but it seems to be incomplete. after checking on the wiring diagrams for another recent wiring project they seemed to be incomplete. I also have a Hayne's manual but for some reason the 85 300td diagrams are nowhere to be found!
