Hi all, I’m in the process of converting my 1.8t ajq from ko3s (originally ko3) to k04 and the ecu from narrowband to wideband I have wired in my 02 sensor plug to the 4 existing wires and added 2 wires to the relevant pins on the ecu. However I cannot find anywhere the pin locations to wire in the egt sensor or the vvt solenoid. If anyone knows the locations or has a full pinout I would be much appreciated.

In september 2017 I made the wideband convertion in my car too, same thing, 2 more wires for O2 wideband sensor, changed the MAF sensor (from final D to L), and its perfect.
I wanna install VVT too, but I didnt find an schematic yet Sad.

i have full conversion and full k04 kit inc maf egt ect and i have a vvt tensioner sat here and plenty of plugs and wiring lol, if we could find a full pinout of our ecu's it would be great!

im not the greatest with wiring diagrams but from what i think i can read on page 6 of the bam pdf the egt is pin 1 on plug to pin 61 on ecu then the next bit slightly confuses me is it pin 2 on plug to pin 91 then pin 3 on plug to pin 109 on ecu? i understand that vvt is pin 1 goes to the 15a wire in the dash harness and pin 2 goes to pin 115 in the ecu. any help to simplify the location i need to trace the wire to would be great as i am creating a proper me7.5 dbw narrowband to wideband guide with all the pinout and wiring locations for 02 harness, vvt and egt, what hardware needs changing etc. i would be happy to post the guide up on here afterwards for people to scrutinize lol. Many thanks again.

N205 (VVT actuator) pin 2 is straight forward. Goes to pin 115 on the ECU's 121-pin connector.
But I didn't understand pin 1. It goes to D102, then to 185 (what is this 185 wtf).
