Cut the cable, shorten it to the desired length, run to radio shack and 
get a new plug, and solder it on.

Keep in mind the most common cause of Firewire port failure is shorting 
the power pin to the data transmission pins by hotplugging a defective 
cable, physically twisting the cable, or soldering the leads on wrong.  
Keep that in mind when soldering your new plug on.

The pin layout is as follows on FW400:
1 Power - Unregulated DC; 12-17 V no load
2 Ground - Ground return for power and inner cable shield
3 TPB- Twisted-pair B, differential signals
4 TPB+ Twisted-pair B, differential signals
5 TPA-  Twisted-pair A, differential signals
6 TPA+ Twisted-pair A, differential signals
