I've searched and not been able to find anything on the wiring differences between the 98 SVT and the 99 regarding the motor.
Finished initial buildup of 99 but I've got a wiring problem

.
I've transplanted my 98 SVT motor into my 99 SVT.
I kept the 98 engine wiring harness on the 98 engine because in August, I'd spliced injector ends into it for the orange injectors with my 2000 LIM. Everything ran great. (before I wrote-off the 98

)
Unfortunately, there appears to be differences between the two harnesses and they don't seem to matchup (i.e. - pin #18 on PCM doesn't matchup, there are several unused pin on 98 PCM versus virtually none on the 99).
If I don't have to, I'd prefer not to pull the intake manifolds and remove the grafted connectors from my 98 engine harness only to re-graft them onto the 99.
Does anyone know if there are only a few PIN locations that need to be adjusted? If so, which ones?
