Is the ls3 harness compatible with a 6.2l l92? Swapped an l92 into my 71’ c10 and I bought a harness then realized it was for a ls3 not the l92.
I have it all plugged in already and my truck cranks, but will only turn on if gas is being poured into the throttle body. It dies right after I stop pouring gas into it. I noticed the injectors don’t have pulse. I’ve tried so many things and the engine just won’t stay on…

I did and they told me it might be possible by using ls3 sensors but i doubt it’ll work since it’s a truck motor and they won’t send proper signals. They do sell another harness that is for the engine but I already have the ls3 harness so it’s kinda late for that..but I noticed the two major sensors that are different from the ls3 and l92 are the crank and maf sensors. Can I use the l92s sensors and maybe change the wiring order or pins on the connectors ?

I can't help with the MAP sensor since I ordered my harness to use the LS3 Bosch style sensor since I swapped out the truck intake for the car LS3 intake.
A couple of other things to take into account is the pedal wiring.
What pedal are you using for your swap?
The L92 has VVT so I don't think the LS3 harness would have that plug for that.
Hope that helps
