That is a tough one, Bob. The 84 manual I have is also published before the late-year change took effect, having nothing on the heated sensor. My '84 LH car has the unheated sensor in the manifold.

I have a full set of 85 manuals including prelim and some technical literature updates, but as far as LH is concerned it takes right off with the 85MY LH2.2 arrangement with the Y-R wire to the dual injection relay as you mentioned. But the LH2.0 system does not use the dual relay (uses two separate cube relays) and no terminal 87/2.

Also, I have one for an 85 740 showing a GN wire supplying the heater from a junction terminal on the right strut tower, but I suspect that is irrelevant except that it is fed from the same source as injectors and idle valve.
