Motronic harness questions on 3.2 conversion

This weekend I unpacked/untangled the motronic wiring harness that came with my 3.2 engine just to see if I could decipher where everything will get plugged in. Luckily, the PO did a nice job labeling the plugs. The only thing I'm a little concerned about is that there only appear to be 2 individual wires that run to the luggage compartment: one with an eyelet for the positive terminal on the battery and one with a spade connector for the tach.

According to Marc's 3.2 conversion thread, there should be a couple more wires going up there. It would seem I am missing 2 wires in particular that would attach to the fuse block - one for power to the coil and one for pin 5 of the dme relay (not sure what pin 5 does though).

The thing is, this harness came out of another mid-year conversion car and was apparently working fine. What should I do?
