ignition problem

hello everyone I am new to jeeps and got my first one recently. I got a 1994 yj wrangler with a 4.0 engine. It has no ac unit and no tilt steering wheel. my problem is it doesn't start when key is in the on position. The jeep was stolen and the thieves cut several wires. I managed to fix them(I hope). I have power to all accessories but will not crank. All the fuses are good at fuse block under hood and under dash. I was thinking it is the ignition switch. Is there any way to test ignition switch? Starter will engage if I jump terminals with screw driver. the Jeep use to run and has been sitting for a couple of months. I noticed some connectors under dash by steering column not being used is this normal. 2 somewhat square female connectors, one is pink(3 pin - 2 black wires and a blue with yellow stripe wire) and the other is black(5pin - 4 wires black with white stripe, black with yellow stripe, black with green stripe and a black wire) Also have about 7 wires coming out of steering column for accessories green, yellow, grey, white, purple and a pink one that is cut(what is this one for) please help I would like to get the jeep going for summer trails, thanks

The yellow wire on the ignition switch attached to the steering column sends voltage to the coil side of the starter relay in the PDC under the hood.

Check the starter relay by swapping it out with the horn relay and see if the horn works.

If it does work then the relay is OK.

Put it back in the starter relay slot.

Check pin 86 of that relay socket for volts when the key is in the START position Pin 85 should be ground. That yellow wire feeds 12 volts to pin 86 of that relay when the ignition switch is in the START position.

I think this switch is for your wipers/washers

The pink wire is for the washer pump motor.

Keep one thing in mind the ignition switch is attached to the steering column by one or two screws It is ADJUSTABLE. That is why your accessories are probably working but the ignition won't start the engine. It may need to be slid up the column a fraction of an inch or so.

Another item you should address.
Note all the surface rust under the dash? Your cowl seal is leaking. Replace it ASAP.

If all that water gets to your dash gauges, fuse box or other electrical items under the dash your troubles will be endless.

Plugs; IF nothing will fit in a plug then you do not need it since that accessory doesn't exist probably.

No two plugs can be mixed up since they are all a different shape and can be only plugged into their respective mate.
