Hello All,

I just received my VR Tuned ECU Tuning Box Kit from Vivid Racing: 2016 Lexus RC300 F Sport. Came with the box, along with wiring harness. Harness has two options (A) and (B).
(A) is for manifold absolute pressure sensor (B) is for camshaft sensor. I'm having a little hard time finding those harnesses in the engine bay to plug into the kit? Can someone point them out to me?

No instructions came with the kit, and what is online is generic..

Has anyone had experience with these tuned boxes? I have an email into the Tech department at Vivid, however, my thought is that I have the wrong harness as well.

Thanks !

 

Quick update!

Skipped the Vivid racing tune along with the wiring harness. Also, customer service sucks at Vivid racing

Picked up a D3 Performance tune (ECU tune) worked out much better, Rev limiter, stage 2 air intake, and pop and bang tune.

Cheers!
