can any one help putting a cosworth engine loon in my rs turbo but need to know what the black and yellow ralay is for and there is a plug in side the car need to know what wires they go to?

Is the plug a small round black one? I think this would be to plug a diagnostic computer into. I stand corrected thogh if someone knows differently and for sure.

 

thanks mate, its not the one i am talking about. Its the big black plug with wires on it guessing one must go to the fule/ pump/ live/ ignetion/ earth and coil.But dont know what one is what and still need to know what the relays are for so i can get them as they were missing when i got the loom.
cheers
