Where do these connectors connect?

[2qik4u]

ok so i know im going to go megasquirt. what I have to ask is who can tell me from experience what the #### are the connector that go to the systems or sensors im missing???!!! ive got a connector that is under the intake manifold that is bright green that has nothing that it is pluggen to. and on the same track of wiring I have another plug that isnt connected to anything. it is about one foot or so further down the wiring harness from the green plug. I also need to know what the plug looks like that goes to the second o2 sensor. there is so much unplugged on this motor its noy funny. does anyone have pics of all the harness connections that label what connector goes to what plug???????? i know my o2 sensors srent plugged but this car is haked i dont know what is what!! does anyone have a diagram about what sensor is what on a 420a????????? my system is really really haked!!! any thing would help!!!!

Your question is really "to what do these connectors connect?" not anything to do with actual tuning...

Pics please (sounds like oil pressure and knock or crank sensor)

I also need to know what the plug looks like that goes to the second o2 sensor.

It looks like this;

4 wire plug that's in the wiring harness that comes across the top of the engine and down around the cam gear side.

This will help you out a little;

and this;
2GNT.com - Acronyms
and this;
2GNT.com - Description_of_the_Stock_MFI_System
and even this;
2GNT.com - Sensor_locations
I suspect that you will also need these at some point;
2GNT.com - PCM_Error_Codes

Also, pics please (of connectors in question)
