Hey all,
I picked up a 16197427 (BJDR) ECM from a 1994 C2500 with a 350/4L80E. Already have new blue and red ECM connectors and KS6 knock sensor. G1 adapter and ZIF socket will cover the chip conversion.
i have been reading through Dave's and Mark's conversion threads and I'm not quite sure what to do with the VSS input. I think the new ECM is looking for a 2k PPM signal on Input F13. Will the existing input on the current 1228747 plug right in, or will I need to find a DRAC/VSSB to work?
I'm assuming that the 1228747 is similar enough to the 1227747 that I can follow the same pin relocations, swap the knock sensor, bypass the ESC Module, and it will work?
