i was thinking about installing cab lights on my 06 2500hd.. what all goes along with that

 

dropping the headliner, laying out the holes evenly,wiring them up right to come on with the running lights,sealing the hole's up good .(would be best with threaded inserts),reinstalling headliner,after checking that it works. first some truck's have a harness up there for lights if it was ordered that way .

 

How hard will the wiring be? it should be in tommorow.. i dunno if the dealership should do it..im afraid of the bill tho

 

And also i have the XM radio antenna up there from factory im guessing it will be ok in the same spot.. its toward the drivers side door

 

depends on how you lay them out ,if you have never done them before have some body repudidable do them or you will live with the problems forever .check how good off quality work they do and there rep for handeling warrenty claims is .
