I've just finished installing the wiring on my 2018 RAV4 XLE Hybrid and now the automatic lights do not work.
NOTE: I've only connected the wires and the EVO-ONE is not connected yet.
I'm using the Fortin THAR-TOY6 harness and I've connected everything exactly as described in the manual:
1) Purple wire to (+) STARTER. (soldered connection)
2) White/Black wire to (-) START/STOP. (soldered connection)
3) +12V and GND wired to OBD2 per manual. (used Posi-Tap connectors; there is absolutely no way to pull OBD2 connector far enough out to solder wires behind connector)
4) "A" harness/passthrough connected to Main Body ECU.
I do not have an EVO-ONE yet but I wanted to finish the wiring. All car functions still work properly except the automatic lights.
What can I check to see why they are not working? I was extremely careful during installation and can't imagine why it's not working except that I don't have the EVO-ONE installed yet.
