do i need the a3 wiring harness as well? or can i just run a2 wiring harness with a3 ecu? also what else will i need to change if the a3 longblock is coming from an auto? thanks!

 

WTF are you asking? You need to tell us what you're trying to install on what car first....

 

hahahaha

 

maybe whats hes trying to ask is does an A2 tranny work on an A3 with no mods?

I think he's basically asking what harness (if it matters) do you need to run in a K20A3 engine with K20A2 transmission setup. Also if he needs to use the K20A2 (PRB?) ECU ?

And I have no idea so someone else answer it

 

k20a2 wiring/ecu if you want reverse lock out.

 

Just throw in K-Pro and your set.
