I did an S4 na to turbo swap and i dont have the na power harness i tried using the t2 power harness but theres a black connector that wont plug in.

Wondering if that is what is causing the car not to start or if my starter is just bad cant find any info on that black connection

Mysteries

(Power Harness is the harness from the battery to the alternator)

 

?

 

So your using a WHOLE TII harness meaning the EFI and main harness side?

There should be no need to swp the drivers side harness out.

Just run 2 wires to the ECU for that one plug on the alternator. Since NA's have that plug on the EFI side and TII's have it on the Main side.

You really need to take a pic so we can see this plug though.

If it is long enough to go to the starter and is a single wire then it is the ingition wire for the starter which tells the starter to switch on and off.

 

yeah ill try and get a picture its weird the T2 harness has one big plug with one connector (Black one) and na engine side has big black plug with 6 connectors

 

ok i got the N/A power harness and got the connection to hook up, there still some wires that wont plug in but think there for tranny. I still turn the key and nothing happens i know theres power when i turn the key i tested it. but from that wire on I have no idea

the signal goes turn key > Clutch Interlock > starter right
