KingCole Posted September 5, 2020 Share Posted September 5, 2020 Hi guys, I am new to the Supra platform and today I started investigating my central locking issue on my RHD JDM Supra mk4. The car is fitted with an aftermarket Viper alarm system which also has central locking (not sure if Supra came factory with central locking) controlled via the remote. The issue was that only the passenger side operated correctly, the driver side locking was not working via the remote. I pulled the door cards off on both doors and noticed that there is no harness connected to the keyhole on the drivers side but there is on the passenger side. If I unplug this harness on the passenger side then the central locking stops working on this side too so I am convinced that having the same harness on the driver side harness would solve the issue. Does anyone know where I can get this harness? It is a 3 wire plug. Cheers Cole Quote Link to comment Share on other sites More sharing options...
ReisenBagels Posted September 22, 2020 Share Posted September 22, 2020 I believe there are 2 types of door harnesses that connect to the interior harness via a blue plug, You should be able to locate this on either side (passenger or driver side), I believe the passenger side has the door control module box which is known to have a common fault: https://www.mkivsupra.net/vbb/showthread.php?355594-Door-control-module-repair I'm also on the hunt to purchase a door loom but can only find 1 person who has it for sale at the moment for silly money which is also on facebook.
