That's kind of what I was thinking. Would anyone know what wires do what on the TCU

I have a 89 comanche with 4.0 (manual transmission) and I recently replaced the engine wire harness but I believe it was out of a automatic comache. Everything went great except one connector on the passenger side firewall. My truck has no spot to hook to but I believe this is the wire that goes to what would have been an auto transmission. I think it controls neutral safety switch. Is there a way for me to make this work on my manual trans? Bypass or new connector maybe?

I know this is an old thread but was there ever a solution? I have the same exact issue and looking for any insight. Thx
