wiring question

[frftw]

hey, i am swapping a ca18det into an s13 and need to know if the dash connector plug (right next to the ecu plug) can be off of an automatic car. i might pick one up tomorrow from a guy parting out an auto s13 and wanted to check if it works. also just to confirm, the wiring is pretty much the same as the sr20 wiring, right? i will get a ca wiring diagram to compare to a ka one but just wanted to check that there are no other plugs that need replacing before i go rip apart the harness.
thanks!
