Here is a picture from the service manual. Connector 16 is the ignition switch connector (First image) The more "life like" second image, the zoomed in 16 and 17 is the connector. If you can get to it and you see it is connected, try to test the wires with a multimeter. The White and White/Black wires should show the battery voltage no matter if the ignition is on or off (as long as battery is connected). If it doesn't, its probably the main 30A fuse.
If it does, try to turn the ignition switch to the ON position. Now test all of the other wires on the harness (except the gray one, which is a security wire) and they should all have battery voltage. These are all BEFORE the fuse box (but after the main 30 A fuse), so these should now have power regardless if the fuses in the box are good or not. If they do not, then at this point, everything points to the ignition switch being bad.
If they do have power and all of the fuses in the fuse box are good, test to make sure 100%. There should be two small metal dots on each fuse, one for each prong. Test both prongs on all fuses. They should all have power when the ignition switch is on. If the fuse does, it should be good. If only one side has voltage and the other doesn't, then the fuse is probably bad or there is something wrong with that wire between the fuse box and ignition switch. If neither do, then it definitely is a wire problem between the ignition switch and fuse box.
If all fuses are good, then it has to be a wiring issue between the fuse box and to whatever device it goes to, for example the ignition fuse that turns on the IC igniter or the dash lights. If so, I bet someone forgot to connect a harness.
Btw, for all of this if using a multimeter, you put the red probe to the wire you are testing and the black one to a ground spot (any unpainted metal part on the frame is fine, as well as unpainted screws that screw INTO the frame). You can test to make sure a ground is good by putting the black probe to the ground you want to test and the red to the + on the battery to see if you get a good voltage. If you do, its a good ground.
Also by what the pics are showing, I'm not sure if there is a place to stick the multimeter in the back of the connector for testings. You really can't test it if they aren't connected. If you can't get to testing the ignition switch, just do the fuse step I mentioned above with the ignition switch on and connected. If there is no power, then it is either something from the battery to ignition switch or from ignition switch to fuse box.
Hope this helps!
