I'm installing an EVO-ONE with T-harness into my 2018 Toyota RAV4 Hybrid.
However, the installation manual (https://cdn02.fortin.ca/download/71281/evo-one_ig_thr_bi_toy6-rav4-hyb_2017_pts_a_71281.pdf)
shows an optional wire for "IDLE MODE" that connectrs to the wiring behind the PTS button?
It says optional but what am I missing if I don't connect it? Is it worth connecting?
Also, even though I've purchased the T-harness, the instructions show that I need to connect to the OBD2 wires for +12V and GND. Do I need to cut these wires behind the OBD2 connector or is there an easier or other recommended place to connect the wires?
