Not sure what year yours is as you still haven't put it in your signature line but..on the gen-1s, most have pulled the storage tray and installed theirs on or behind the dash framing as well as any additional relays needed. As for power you will need to run a separate fused line to the battery, anywhere from a #10 to #6 depending on the total load requirements. Then for circuits requiring keyed power, just use the acc plug power to trigger relays to those loads.
