I recently purchased a Greddy AP2 kit(04-05?), i need to mod it to fit my AP1.
Anyway, I know that the harness must be modified per Chris Lum's posts on s2ki. However, i cant seem to find which exact wires must be interchanged. Can someone please push me in the right direction.

here you go, the harness modification i posted a while back was incorrect. Benny (My manager while i was at GReddy and the E-Ultimate Guru) sent me this diagram. Hope it helps!

 

Someone should sticky this...

 

Wow, that's easy.

 

Does anyone know what the 2 wire plug is for on the harness? I have 2 wires with a plug attached to them that doesnt hook up to anything...

 

I believe those are for extra gauges and such.

 

bumping an old thread.
my long harness that i has a gray wire that goes from the emanage to the ENG harness and the yellow wire does too. I just connect those 2 wires to make this work on an ap1?

basically i dont have a single yellow wire from ENG to ECU with this long harness.... all the wires from ENG to ECU are yellow and the ones that go to the emanage are color coded.

???

 

you don't need to modify the harness ( although the above instructions are correct if you want to modify the harness)

Just set the Analog voltage map to have the same numbers on the top row as the bottom.


You will need to leave the parameters setting the same but you will need to updated the fuel and ignition maps.
