Unneccessary wiring under the seat, How do i remove it? Options

[wbergtho]

I have a heavily modified V-8 car and I've got the seats out and the gay wiring that controls the seat belts under the passenger side seat. I've already spliced the primary ignition/starter wire (big yellow wire) and removed it from this area. my question is, what do I need to know before i cut the rest of this worthless rat's nest out? Is there anything else in there that I should concern myself with?

Thanks,

Bill
