1995 Isuzu Trooper Questions.
 

So i got a trooper, and i put in a new head unit/speaker system, i ran wires under the steering wheel, and when i plugged the battery back up the illumination lights wouldnt come on, at first i thought maybe it was the lights blew, but then i realized that none of the switches lights came on (hazard, cruise, stuff like that) the clock dims but thats about it. The only thing i can think of was maybe i pulled a wire somewhere, but i checked everything i could see. and i ran the dimmer light wire into the tail relay wire when i set up the new radio, so i thought maybe it was that, and undid it but nothing. Does anyone have a detailed wiring diagram of the lighting system, or at least a picture of the lighting switch, because i dont know what that is and the repair manual i have for it says to check that, any help would be amazing.

Thanks.
