2G 64 in place of a 63?

[Gearhead4G63]

Hey guys I was wondering if I can use a 63 harness on a 64 motor? I know I would have to change the ECU. I bought a GST with a blown motor, I have a running 64, can I drop it in without changing the harness? Are the pins on the ECU's the same, so would the GST harness work, till the 63 is rebuilt?

I wouldnt think it would be much different. Install the knock sensor in the block.
