Engine loom to body loom connectors

[steve-V8s]

The standard engine loom predominately goes from the ECU to engine stuff. injectors, coil supply, temp sensor etc. It also splits off just after passing through the bulkhead into two connectors (I think it is two, I can feel them but have not yet seen them) I guess this is things like the Rev counter drive, temp gauge, alternator charge warning light, and coming the other way road speed sensor, switched and probably un switched supply and some things I have not thought of. Does anybody have a drawing of the pin out and colours of the two connectors?
