Non turbo with a 7mgte

[Semper_Fi]

Thanks again supra forum, for all the help.
I just finished my supra, and im about to insure it, but i can't figure out why the interior won't get any electricity. Like the radio sometimes will kick, but not turn on. My headlights stay on, and the nothing inside the interior wants to respond. Now what should i do, or look for. Is it because my supra was made into a 7mgte? Also my gauges never worked... How should i fix this. Im not very good at the electrical...anything. The people in my avionics department want to take a look at the car, but I dont find it too safe to be driving a freshly rebuilt engine 2.5 hrs with no electrical power... thanks again supra forum.
