Is it a later 316 with a C101?
If so there are two wires you need to cut on the ECU plug and then connect to the C104 plug which will now be unconnected following the removal of the old loom. The easiest thing to do is cut the matching plug from the old loom and plug it into the loose plug in the car. Then you need to connect pin #1 (Blk/Blu) on the C104 to pin #6 (Blk) on the ECU, the second connection to make is to connect C104 pin #3 (Wht) to ECU pin #32 (Wht/Blk), C104 pin #2 is not used. This is purely for the instruments.
You need to fit the return fuel line then just use a later intank fuel pump, one with the return on the top like on a 318iS. Then find the unused fuel pump connection underneath the rear bench seat, extend them slightly so they will reach the intank pump and then fit the fuse in the fusebox.
