93 olds 3.1l will not start. Please help,

Hello, I will make it short. I have a plug coming from the firewall on the drivers side, two wires, high above(or next to the brake booster)and seems to want to go down near the bell housing? It is long enough to go past the MAP sensor straight across, but I cant find where it goes. I have tried to trace the wires but no luck. There is another plug that T's off from the plug for the mass air flow sensor with only about 1" of slack right near the end of the plug. Thanks for any help. I can email a picture of the plugs if anyone can help. Thanks.
