After searching threads for hours and messaging people directly I decided to make my own thread in the hopes someone can help me as I am desperate and tired.
Back story
I did a manual swap on my FD ended up using a haltech ecu as well. The date the car was finished I took it for a drive the cluster lights were working. Mid way into the drive my cluster lights randomly shut off. When I arrived home I noticed that neither my dash nor my tail lights had power. Oddly enough brake lights work as well as turn signals. I then noticed that my cluster lights up when i turn my key to the on position but as soon as I start the vehicle the cluster shuts off. My Interior cabin lights work as well as other lights such as the key entry light as well as my cigarettes' lighter.
Attempted Solutions
I went ahead and checked on the TNS relay and noticed that it was functioning. I went ahead and cleaned it off just incase it was dirty.
I will be inspecting the headlight switch harness in the morning.
I have been at it for days hoping by the time I get a fresh start at it people will add in ideas.

Start by checking all the fuses on the car. If that doesn't solve it, find a copy of the factory wiring diagram (in the FAQ thread) and spend some time learning how the system works. IMHO the hardest part of something like a transmission swap or ECU install is getting every single circuit correct both electrically and mechanically, without causing unintended side effects.

Different circuit for Stoplights, cluster, and Taillights. Taillights are TNS relay through the 15A Tail fuse and circuit. Stoplights are through the 20A Stop fuse and circuit. Turn signals are on the 15A Hazard fuse AND the 15A Meter fuse through CPU #2 and then to the turn signals. Cluster is on the 15A meter fuse. Work the 15A meter circuit. Replace that fuse for sure. CPU2 may be on its way out as well.
