Help PMI wraith

[rmb7]

I was pming a wraith and its my first time to pmi. The tut said to copy the code from the writh into the tank. But I dont want to copy it into any thing I just want it to be its own vehical. I tryed injecting that tag into the senerio with se but it just came out as a square cube. Can someone tell me how to make it its own vehical please.
