Bob, Have had a bunch of FI 111 bodies. No two were wired the same. They had 1 and 2 solenoids on the FI pump, thermo time delays, Temp sensors, CSV, yada, yada. The manuals showed different wiring diagrams for the same basic relay and solenoid setup. MB was looking for the right combo!! Does the fuse box cover give any clues? Usually they refer to what functions are there. As I remember each relay had a good chance of being on a different fuse.
