said cable comprises a first portion terminating in said first connector, and a second portion terminating in a second connector, said second connector being connectable to said component.

4. An integration test station in accordance with claim 3, wherein:

said cable comprises a third portion terminating in a third connector, said third connector being connectable to a jumper plug.

5. An integration test station in accordance with claim 4, comprising:

a jumper plug connectable to said third connector, said jumper plug providing selective interconnections between said plurality of conductors in said cable when said jumper plug is plugged into said third connector.

6. An integration test station in accordance with claim 3, comprising:

an interface test adapter coupled between said second connector and said component.

7. An integration test station in accordance with claim 6, wherein:

said interface test adapter comprises a plurality of loads connected to predetermined ones of said plurality of conductors.

8. An integration test station in accordance with claim 7, comprising:

a holding fixture for receiving said component.

9. An integration test station in accordance with claim 1, wherein:

said vehicle comprises an aircraft.

10. An integration test station in accordance with claim 9, comprising:

a simulator card coupled to said central processing unit;

a cable having a plurality of conductors;

a first connector coupleable to said simulator card, and

said cable being coupleable to said component.

11. An integration test station in accordance with claim 10, wherein:

said cable comprises a first portion terminating in said first connector, and a second portion terminating in a second connector, said second connector being connectable to said component.

12. An integration test station in accordance with claim 11, wherein:

said cable comprises a third portion terminating in a third connector, said third connector being connectable to a jumper plug.

13. An integration test station in accordance with claim 12, comprising:

a jumper plug connectable to said third connector, said jumper plug providing selective interconnections between said plurality of conductors in said cable when said jumper plug is plugged into said third connector.

14. An integration test station in accordance with claim 13, comprising:

an interface test adapter coupled between said second connector and said component.

15. An integration test station in accordance with claim 14, wherein:

said interface test adapter comprises a plurality of loads connected to predetermined ones of said plurality of conductors.

16. An integration test station in accordance with claim 15, comprising:

a holding fixture for receiving said component.

17. An integration test station for evaluating a design of a vehicle component, the test system comprising:

a central processing unit;

a first test instrument coupled to the central processing unit; and

a memory coupled to said central processing unit and comprising models, the models corresponding to vehicles,

wherein;
