I took the Hensley True Control Gold brake controller from the old Tundra and using the Nissan's harness, hooked everything up, double checked with Hensley and Nissan to make sure the right wires were matched.
Problem : The controller only displays information when the brake pedal is applied. When I release the brake, screen goes black again. So I can't control gain or monitor any voltage, you know, basically use the controller. I checked all the fuses and they are good. Is this a relay problem? There is no constant power coming from the Nissan wiring harness RED wire.
Any ideas?

This is likely the problem. If the vehicle is used it may be gone. If it is new you may want to look. As suggested above there may be a tow package kit (relay, fuses, etc) that has not been installed. This (Ford version) is a bag of parts either under the passenger seat or in the glove box. It is part of the tow package.

This may be what you are saying about No power to the red wire. A quick check would be to see if there is constant power on any of the wires coming out of the Nissan connector. That would be the one the to connect to the black wire on the controller.
According to this page I would suggest checking the voltage at the black wire going into the controller.
Without totally tearing your connections apart see if you have 12 VDC at the black wire connection.
If you dont have 12 VDC you need to trace that wire back to its source. You indicated that if you hook this to a battery directly it worked as expected.

Perhaps you need to install a fuse or breaker to activate the red wire? Some of the big 3 trucks require this to activate the brake controller circuit.

Sounds like you have hooked the brake trigger wire to the power in wire on the unit.
That was my thought as well.

Have you checked the factory harness color code? It maybe different color code then the controller harness.
Verify Nissan and controller harness, Splice accordingly.
Also, you might try one of the Titan specific forum like titantalk.com, etc. for more info.

All I found was this:
FOR NISSAN JUMPER HARNESS :
Red/green = vehicle stop lamp switch to trailer brake controller
Black=brake controller ground
Brown/white=trailer brake controller switched output
Red/blue =illumination
Red=fused trailer brake controller battery feed (B+)
