s4 na to TII conversion

ok so i looked around and all i could find is people saying that i need to
1. keep the s4 na wire harness and get the aspec TII ecu
2. Get the aspec ecu and TII wire harness

Now my question is the swap i would be getting is the s4 jspec comes with the jspec ecu and uncut harness. The jspec wire harness will be 3 feet short but if i use the same gauge wire and insulate any ignition related wires can i just use the jspec ecu?

also i picked the car up for $200 with a clean body, it comes with no motor, tranny, wire harness

The n318ecu gives some people issues. Just find an n332 or n333, not particurlary expensive. I swapped a t2 engine into my s4 with no issues at all using the na harness. HAILERS QUOTE "it makes no sense to use the t2harness when swapping in the turbo engine. Search for HAILERS and harness....get some coffee and read. Fairly straight foreward and less work only a tps wire extension using na harness as opposed to ******* with alternator wiring with the t2 harness. See if either japan2la or atkins will give you some money off minus the harness.........those are the ONLY 2 distributors you will consider buying from.

I've spent three hours looking for the post about what you have to do to your N/A harness to make it work in the TII...
Anyone have a link or just some pictures? Any help would be much appreciated.

Thanks,
Scott

1. Cut the wire at pin 1R (knock sensor on turbo ecu, but p/s switch on NAs)

2. Extend the TPS wires

3. Extend the BAC wires

I found all of this info on here before I converted my car. There are a bunch of threads.
