95 318ti "electric sensor connectors" HELP

[Wyvern]

Hello .

I had to do a starter replacement .. (Wow that was fun ..)
I did it not in my garage and an emergency repair..

Issue is that I got the sensor connectors mixed up.
Car runs fine but I have no tenp gauge signal and the check engine light is on.
So I need to remove the manifold and plug the right connectors in at the right place.

Upon removal I thought they were color coded or "keyed" (they arn't)
any help in figuring out what connector goes where . can I cend a signal and test ?

I know that there is a temp sender.
maybe a nox sig
and if I remember right 2 others.

Thanks guys.
