Auto body repair & detailing: 1999 Camry radiator support replacement, radiator support, fuse block

Question
I am attempting to replace the radiator support assembly in a 99 Camry.  So far I'm doing OK with disassembly, but the wiring harness runs out through the driver's side headlight hole and is supported on the underside/outside of the radiator support, then back in through the passenger's side headlight hole of the radiator support.  Since the replaement part comes as a assembly, how do I get the wiring through this.  I can dissasemble the entire fuse block and harness, but this seems pretty hard.  Am I overloooking this easy way or what?

Answer
JIM......OH WHAT A FEELING AS TOYOTA SAYS......I'M PRETTY SURE ON THE OLDER CAMRYS THAT YOU HAVE TO REMOVE THE WIRING TO COMPLETE THE CORE SUPPORT INSTALL....SOME MODELS THE WIRING CAN BE REMOVED FROM WHERE IT GOES INTO THE DASH BUT THE DASH NEEDS TO COME OUT..IF YOUR PARTICULAR VEHICLE IS NOT WIRED THAT WAY THEN YOU ARE CORRECT, THE FUSE BLOCK HAS TO BE DISSASEMBLED.
