Ls2/ls3 harness in a Gen3?

Still looking for a project car/truck for my engine.
I have a complete l92 engine with l76 intake with 8k miles from an 08 escalde. I ended up selling the heavy 6l80e about a year ago, shoulda kept it.
I have the whole engine harness and PCM. Wondering if anyone or if it's possible to use this harness. Trying to avoid using the leignfelter harness, and don't want to tear it apart just yet to change the reluctor.


Edit meant to put ls2/ls3 in the title

Also I'm thinking about getting a rcsb or SSS (if I can get a deal on it).

How close are you to San Antonio. i saw a clean 05 CCSB for sale. Not sure if you want a CC as a project though.
