Burnt wiring harness by turbo

[bus2nut]

I have a 1982 3208t cat in a 35 foot wanderlodge.The power stering
reservoir hose was burnt and I moved it to the front AC comptessor
location.I installed a heat shield on the turbo and cross exhaust
manafold.I changed the tranmission shiftdown cable,Burnt.The wiring
harness is brittle and insulation coming off.
Has anyone had this problem or re-routed the wiring?
There is just enough room to put you fingers between the exhaust
blanket and the dog house.
