oop: that suck's
Do you have a volt meter?
Did you use a pre-made harness?
When you say doesn't have power do you mean with a volt meter or the head unit just doesn't come on?
Is it correct to say everything works (including the dome light) except for the HU and the door locks?
If you didn't cut any wires can you plug in the old head unit for testing?
Did you check both the car fuses and the new HU's fuse's
I don't think you have a major electrical issue yet.
I think I vaguely remember something about the alarm/power lock and stereo connection I'll try to look it up.

Notes:
NOTE: Jeep vehicles that use a gray ignition key have an immobilizer system that needs to be bypassed when remote starting. Use DEI part number 555C or 555U. *1 Lock is negative trigger thru a 1.4K ohm resistor and unlock is negative trigger thru a 426 ohm resistor. MUST use relays. *2 In the top left corner in a black plug. *3 Parking lights is negative trigger thru a 910 ohm resistor. Headlights is negative trigger thru a 349 ohm resistor. MUST use relays. *4 The driver door trigger is tan and the passenger door trigger is tan/white, use both wires and diode isolate each. *5 The factory alarm disarm is negative trigger thru a 473 ohm resistor. MUST use relay. *6 The BCM (Body Control Module) is attached to the left of the fusebox. Connector 1 is a gray 26 pin plug, and connector 2 is a gray 22 pin plug. *7 The flip up glass pin switch is yellow/white in conn. 1, pin 9 of the BCM. *8 On vehicles with the premium sound system, each speaker is individually amplified.
