running engine on stand?

[BilLster]

ok i just realized this time i cant really swap engines in and out of the car . i have a new 393 twin turbo setup i was going to try and tune on the engine stand .

I geuss i need a complete wiring harness and computer .
i have a trex pump run to a sealed gas can. stock maf and other components exhuast run out of the shop etc .

not sure what i need to connect to the harness . ie fuel pump (normally hard wired to switch on stand) maf ,injectors tps .
o2 sensors.

i will be looking for a harness and computer next weekend at the wreckers.

Anybody know any problems with running the engine this way ?
it wont be going into the car untill spring . (or i get another car.)
