mystery wires !

[i heart square bodys]

another question from me that can hopefully be answered ! there is a single wire coming out of my firewall. this wire was connected to a series of wires that went to my transmission, it also spliced off onto an orange clip, I don't think this clip was ever hooked up either. I have removed all of the wiring up to the black and the orange clips because I am planning to install a B&M lock-up controller instead of the stock lock-up controls. what do these remaining wires do, where do they go and why? if it is a power wire I may run my lock up controller off of it if possible .
thanks!
