Connector at fire wall

It might be the test plug you use to see if the electric fuel pump works when its relay and oil pressure cut off switch wiring goes faulty--I never owned a EFI truck,I only know that from reading about it here on other posts...maybe a search will bring up a result...

Yea I have two mistery green wires and I was thinking just maybe one or both should be connecting to this area....
 
I have it on my truck, I'll have to look tomorrow after work to tell you were it goes though.
 
That gray plug has a mate.....And the mate has 2 green wires. (Ignore the single green wire to the right, that's a ground for something else.)



One green wire goes down.......



to another gray plug, that is coming out of the wire wrap towards the bottom of the firewall. Bet it's for the A/C switch.



The other green wire goes to the plug for the A/C compressor. That wire might be in a wrap/protector sleeve. The second wire at the A/C plug is for ground and should come out of the sleeve and connected to the engine/head. (I replaced the last photo with a better, focused pic.)

awsome, I think this solves my mystery wires..... Now the impossible would be to find someone who has some of these factorty connectors so I can make it right....

thanks
