multifunction switch/ cps crankshaft position sensor, no gauges, etc..

Hey guys. I've spent two days searching all the threads, and I'm still stumped. Background: Recently the fog lights were coming on randomly. Playing with the switch/lever temporarily made them go off. After researching, I replaced the multifunction switch. At the same time (and while charging the battery out of jeep) I replaced the headlights. Now it won't start. Turns over, but won't run. I checked all fuses and relays. No gauges. I bought a code reader, and it only reads "no link". The self diagnostic (hold odometer button, then turn key on) only reads "bus 60 panel open". From what I've read here all signs pointed to a bad CPS. It seems odd for that to coincidentally malfunction right after replacing multifunction switch. I replaced CPS to no help. I spent the rest of the day checking connections and looking for frayed wires or bad grounds. I don't know if I should replace the cam shaft position sensor, or just give up and have it towed to a shop. Any help or suggestions would be appreciated. Btw: 2001 wrangler, 4.0, manual tran.

Thanks, Bill

Unplug the Crank sensor and see if the gauges come back to life. A shorted CKP (or any of the 5 volt sensors) will shut down the computer. A no bus message means there is no connection on one of the communication lines the PCM uses.
