Resolved What are these connectors / 1990 GS-T

[teme]

I have dropped newer model engine to my 1990 gs-t. Having some difficulties identifying the connectors from the original wiring harness, and as I'm lazy, thought I ask you guys first before I start to go through the service manual

See the attached pictures

Picture 1: Harness is behind the intake manifold
Picture 2:: For CAS?
Picture 3: The one in the front, and the lower one not connected in the firewall.
Picture 4: Fuel pump check connector etc?

Cheers.

The first one spade looks like brake resivor
2 looks like it goes to the reverse switch connector
3 maybe transistor pack, kind hard to tell
4 i never used it in any dsms ive owned ive always seen them disconnected
