What year is the harness, just to get a better idea of what valves you need.
I think the only ones my 3.4 had was the ones on the evap canister. I used the 3.0 vsv valves for the 4x4.

Yeah the only VSVs I believe I am using are the 2 mounted on the EVAP canister, you can run the old 3.0 EVAP system. Check Beckinrajs thread (I spelled that wrong) You are going to need that ECU! I don't know what your plans are but you should grab that if its still available.

Thanks guys, it is a 98 3.4 going in a 89 5 speed.I found a ECU on craigslist.I didn't know that you could use the 3.0 evap system.I am still a little afraid of the wiring but there is so much info on here i think i can handle it.

I know that Elvota has some good info on this and it was helpful for me. Pictures with callouts were hugely helpful...
