I converted my s4 se to an s5 turbo(.Motor is from japan.) I changed out every wiring harness in the whole vehicle. all is t2 except engine harness.(which i was told how to hook it up and just not use the stock boost controller)I got it to run but the power cuts out. also there is a ground wire that goes from the firewall to the trans. that seems to have melted from the inside. I am not good with wiring at all. is there anyone who might know what is wrong.. or how to fix it. if there is anyone in utah that is willing to come check it out or fix it, it would be appreciated.
thanks

 

Take my advice its not that hard to find an S5 wiring harnes why would you change all the others and not , well to me, the most important the one that goes to the engine????

 

if anyone has a s5 t2 harness(engine harness) I would buy it. i cant find one. I've looked for them and there arent any here in utah. i havent found any on this site of any other site (except for a couple that are burnt to ****). so yeah if anyone has one ill buy it.
