The connectors plug in, but the pin out is different. You have to swap several wires around in the connectors.

Sevral = ~ 153/160 pins. Then there is the fuel indication, if you are using EFI Live you can correct it with the software. Bottom line, this is not a plug and play type situation. Lot's of folks (not necessarily in this thread)reguratating (false) info on this subject, very few with actual hands on experience and success. It can be done and is well worth the effort. Good luck.
