Hey I'm building a drag 2003 mustang which is gonna get a 5.4 4v the only thing im worried about is wiring since the sn95 i have is a v6 so what I'm asking is which harness should i get will an engine harness and PCM from a 2000-2004 cobra work?

Thanks

 

If I were you ,I will use a FAST stand Alone or a Bis Stuff 3, MoTech is also a good option for a DRAG car

ps#you can make it work with the cobra stuff,but I will not use it....

 

You can rewire a gt harness and use a gt computer that is reflashed with a programer.

 

the reason i was asking if i can use a cobra harness and pcm is that because i only know how to tune by using SCT advantage and i have never tried something else. and damn those aftermarket engine management devices they are very expensive

 

i also forgot to add one thing by saying a drag car i dont mean a 7 sec car or anything crazy my goal is just to reach the low 9's or if im lucky the high 8's

 

just get a standalone if you can tune sct advantage you can do a standalone. you will end up being cheaper in the end and have way less issues tuning. i have also seen way too many motors blow up because of the stock computers that i would not trust one especially if you have to wire an ecu anyway

 

hmm looks like im gonna go with a standalone MMR has a nice F.A.S.T Xfi package for 3000$ if i get the FAST is there anything else i should get?
