Darren M Posted April 27, 2022 Share Posted April 27, 2022 Hi Im trying to install this Toyota head unit into the Supra but the outlets on the rear do not match the plugs on the oem wiring loom. Am I going to need to get two plugs to fit the new head unit and use like an iso block to connect it up. My car is basic sound with no subwoofer or amp under the seat. I have found online a wiring pin out which looks similar to my head unit. Any help greatly appreciated. Thanks Quote Link to comment Share on other sites More sharing options...

Darren M Posted April 28, 2022 Author Share Posted April 28, 2022 Is the left hand 12 pin output for an optional CD changer in which case I only need to use the 15 pin outlet ? Quote Link to comment Share on other sites More sharing options...
