Progress report:
I've gathered most of the parts I need - I think! I have:
'85 1200 LTD main wiring harness and fuse/relay box.
LTD fuel injection sub-harness and ECU computer.
LTD intake system (plenum, throttle bodies, throttle linkage, injectors, intake tubes, fuel rails, secondary air system, idle air valve, and air filter & housing).
LTD fuel delivery system (fuel filter, fuel pump, pressure regulator and hoses).
LTD sensors (crank angle, cam angle, R & L intake pressure, air temp, coolant temp and throttle position).
LTD thermostst housing and water pump cover.
1200 heads, cams, valves, covers and sprockets.
A plenum from a carbureted 1200
I'm assembling the system on an empty - except for the crankshaft - 1100 case. I cut a 14mm section out of the carburetor plenum (the injection system plenum is becoming a rare part) and the the fuel crossover pipe.
I used good ol' JB weld to hold it together. It may be temporary, or it may last forever.
After being amazed that my measurements and cuts actually worked out, something else amazing happened! The longer 1100 throttle linkage fit on the narrowed side! A slight adjustment of the sync screw, and all 4 throttles are closed. The air valve, which is coolant temp and computer controlled, controls the idle speed.
The crankshaft angle sensor, using the tabs on the center wheel, sends 8 pulses per revolution to the computer, helping to control ignition timing and injector timing and duration.
There are no mounts for the pickup coil on the 1100 case. This is another challenge...
Little by little, it's coming together. Once it's all put together and wired, I'll hook a 12 volt supply to it. If I hear the injectors click when I turn the crankshaft, it works!!! Then it goes into the '83 test subject. Mmmmmm...fuel injection!!!
