94 sl500 codes and the dreaded harness rot

[edsl94]

hi fellow sl owners. i have a 94 sl w/56k on the odometer, and a 119.972 motor. upon a recent restart the car ran very poorly. got it home, read some threads, made the blink reader( it works perfectly) and pulled some codes from the 38 pin connector. they are as follows:
p4=0
p6=0
p7=6
p8=0
p13=constant l.e.d.
p14=constant l.e.d.
p17=12
p19=6
p21=17
p22=constant l.e.d.
p23=15
p31=0
pins 11,30 issued no response
upon a clearing attempt p6 cleared, p17 cleared to a constant l.e.d.,
p19changed to 7, p21 changes to a 7. also the cel cleared on the dash.

as long as i had the engine exposed i did a closer inspection of the wiring harnes and anyhting not "on" the engine looked fine. but there on top of every injector, the dreaded harness rot. exposed wires just aching to short. do i blow it up now or is there hope?
