wiring harness differences

I have the 69 C10, originally a 6 cylinder 3 ott. The wiring on it was good.
I swapped in a 350/T350 and recently began hooking the wiring up and found some differences. I see the standard trans backup light switch was hooked into the trans. The 71 w/auto trans harness has the bkup switch/neutral safety switch located inside on the lower steering column.
One other difference I see is the wire harness across the radiator support has a couple of inline fuses in the 71 harness that my 69 harness does not have.
The schematics I have found here for 67-72 are different from what I have.
I do not intend to buy a new harness. This is just a driver.
