i just got an s4 tII with it came with out a wiring harness i was wanting to know if there is any way i could use my na harness temperarly until i can afford to get the tII wiring harness

 

Yes. Just connect it up. Turn the key to Start and go for a ride.

Never use a TurboII EM harness unless you want to do a bit of rewiring to that Turbo EM harness.

EDIT: You got WHAT?????? A series four TurboII car with no EM harness for the motor? Or got a Series four TurboII motor? And are putting it in a non turbo car? Or got what?

 

no its just the jspec motor i am putting into my 87 na

 

The only problem would be if it's a series five motor. IF so, it has an electrical OMP. The electrical OMP won't work off a series four ECU.
But you could premix in lieu of the OMP working.

 

its a series 4 tII that i am putting in to my series 4 non turbo
