If i were to purchase the 1.3u cable and then get the wrx connector so i could also flash my friends car, how do you get the wrx connector to work? Do i have to solder it on or does it plug in the top?

Sorry if it's a stupid question I just haven't been able to find an answer or figure it out anywhere...

 

I think neither ... I think the WRX reflash connector plugs into a separate connector port.

 

So how could i use it if i got the 1.3u?

 

Quick google search revealed this:

But you're asking for help on the wrong message board ... try NASIOC instead.

 

I believe the actual cable is compatible for wrx without any further modifications, from what I have heard, and seen .

 

All explained in the links I posted above.

 

Alright, thank you!
