drawing from memory here, but I believe the 8062 series ECMs have a similar pinout- my 4.3L V6-factory-powered 89 S10 Blazer ran that ECM in stock trim. When I installed the 5.7 TBI motor out of an 89 C1500, I just unolugged my ECM and plugged the one that came with the motor (7747) in. The only "wiring" I needed to do was elective- I extended the entire harness by 3' for peculiarities in my application. Didn't have to cross any wires, move pins, or anything.
That said, I couldn't tell you if you could go color-for-color between the two ECM pinouts, but the wise swapper will ignore wire color for pin-header position.
