I am cleaning up the engine bay of a 91 2.1 westy, 2wd while the engine and trans are out. 
In the engine bay on the firewall about where the Tstat tower is, there are two yellow single wire connectors coming out of the 
main wire harness across the firewall. Each connects three wires together. One has 3 green  wires which I think is T1h seen in the Bentley
wiring diagram near the hall generator. The second connector has  3 gray wires which I can’t find on the diagram. Any ideas?
These connectors are very corroded so I am cutting them out and going to solder the wires together.
Thanks for all of your knowledge.
