5.3 swap wiring 4L60e to 88 NP241

[75K5]

I am wiring up my 5.3motor, 4L60e trans, and 88 NP241 to be installed in my 75K5 Blazer. I've come up with the following questions

1. Where do I wire the VSS signal to on the ECU? Doesn't seem to be a place for it since the np241 has a mech speedo output

2. Were do I wire the oss signal from the ECU?

3. Where do I wire the 2WD/4WD signal from the ECU?

Thanks for the help!

Didnt the older speedos use a vss style output for the cruise control? i may be wrong.

And someone may want to swap your mech style 241 output for their electric 241 output. That or ive seen those inline vss adapters, but i dont know how recommended they are.
