Thanks Carcinogen: My block does in fact look similar to the 1980 type block, but where the 4-way would go there was a wire coming out. I"ll compare the picture to actual later tonight. Is it possible there's yet a different layout for 1985 - I found a wiring diagram and it looked like there was a separate small block marked "convenience center" in that. looks like the cigarette lighter and 4-way and maybe one other thing were in that location. I didn't find anything under the wheel behind the service panel other than what looks like after market cruise control. may have to grab a mirror.
