Ford Transit´97 electrical system problem

Hello, I am Neuvado in this forum and I wanted to know if someone could tell me how is the electrical scheme of the engine of a Ford Transtis of the year 97 because I am missing a couple of cables to connect and I do not know where they are connected.
Thank you very much in advance and I wait for a fast answer

Explain better that you need those cables from which side of the engine are they start the engine or not?

Not the engine does not start. The keys are on the right side of the motor that leave the battery side, and I have connected the keys of the alternator, those of the start, the temperature and one that goes in the change.
And I have to connect a plug that has three cables and another that has only one cable but I don't know where I go or removed and we don't know where they have to connect
thank you very much

When you turn the key, do you turn on all the lights in the instrument box? The cable is thick, pede to be the heater.

Thank you very much for trying to help me but it is already solved it was that it is diesel did not heat it because this model is without heater so it does not hush us and it has also cost us how to baro it but Aora already ba as a shot thank you very much of truth the next doubt that you have already to find it
a greeting to all
