Hi all i have posted this in the right category but no help.
Just wondering if evoscan works with a 1995 wrx? And would it work with the diy lead ive seen in a thread, it is made from a usb lead and a legacy stereo harness? Or do i need the evoscan cable.

If this doesnt work does anyone know of software that will work? Needs to be pre obdII type. I think its ssm but not sure if ssm2 or not. Ive got a yellow plug under my dash next to diagnostic plug

 

Also what processor is in a standard ecu? Is it either hc 16 or sh2. Basically asking if ecuflash will work?
