I have a 92 honda accord with h22a swap, I have power to my fuse box under hood but no power to the inside/ignition inside the car!!! what main harness give power to the in car fuse box/inside car????

checked fuses inside and out checked plugs.....over and over again....

 

have u check your fuses maybe one is blown,there is a solid yellow wire,and a solid white those are main power to the inside of the secondary fuse box the one inside the car.folllow the wire maybe u have a short somewhere in the system.

 

you need to get a good wiring diagram and follow back to see how the ignition system is run. Check and corresponding fuses and check for power up until the ignition switch and even after to find your problem. However a good wiring diagram is what you should be looking for. Also some good tools would be a test light and a multimeter.
