depending on the tool used to pull codes, if the car was NOT running, the crank sensor code will post. i've used generic stuff in the past and this has always been the case. if the sds was used, i'm not familiar with what it will do with the motor not running.

on the harness issue, there's more than 1 needed to fix the problems. i've not done a v8 but on the 4s and 6s, there's another harness for the trans and maybe the ac. on the 4s, there's 1 for the coils. the harness attached to the throttle body suffers the same way, you'll need a throttle body. the main harness on the v8 won't replace everything under the hood coming apart. any flaking seen means you need a harness or 2 or 3. good luck, chuck.
