c 280 rough running

my car continues to baffle me. I ran the codes with an LED. It has the 38 pin connector. pin 4 had no codes. Pin 7 has code 7 which is:
CAN data bus signal from EA/CC/ISC, ABS/ASR, HFM-SFI, OR LH-SFI control module faulty.

Looks like it may be the old harness issue. However, the wiring looks good and doesn't appeat to be brittle. For example, the lead from the HFI going into the computer area seems supple. Is there anything to look at before doing the harness. Any suggestions as to a harness supplier?
