Hey everyone,
I'm building an LS-powered '91 Z07 coupe for CAM-S. I'd like to keep the ABS functional, so my question is what info does the ABS module get (if any) from the factory ECM? Vehicle speed? If I can figure out what it needs I should be able to supply it with the proper info from the LS ECM.

Thanks for any help!

You need FSM so you can identify your wiring during the swap. The ABS isn't tied into ECM since it doesn't have ASR/traction control. ASR came with the LT1

My service manual is with the car across town right now unfortunately. The car is being used to prototype LS and LT engine mounts and headers by an LS conversion kit company owned by a friend. They haven't done a C4/LS/LT kit yet - and my car is the guinea pig. Once they're done I can actually get back to building the car.

Anyway, that's good news. Thanks for the info Kevova!

ABS has no tie in with the ECM. The closest you would get is the VSS, that is spliced before the ECM/CCM connections.
