I am putting an 02 ls1 in my 96' s-10 truck. The 99-06 fullsize trucks have a high resolution rear speed signal that is used by the abs unit for the rear wheel speed. On the 99-02 trucks it is in c2 pin 49 on the pcm with a yel/blk wire. Since the pcm's are the same service number I assume the pcm has the capability I am just not sure if it is an output that is always active or if you have to turn it on. Does anyone know if this output can be activated using the HPT software or is it already operational in the f-body pcm. Thanks
