While I have been able to trace the majority of the terminals on the 4 plugs on the digital dash, there are a few remaining that I am not sure exactly what they do. I have followed them on the wiring diagram but I am not sure what their purpose are. Does anyone know?

Plug 4, Pin 1 - Terminal 15 Cargo. Exactly what does this do and what is different from regular ignition power?

Plug 4, Pin 6 - Speed. Is this the input for the speedometer?

Plug 4, Pin 7 - Terminal TD. What is this?

Plug 2, Pin 10 & 11 - Radio TX/RX. What is the purpose of these connections?

Any insight would be greatly appreciated!

Cheers!
Carl

 

My guesses ...

Plug 4, Pin 1 - I have it noted as "Term 15 to CE" which I believe is 12V switched power?
Plug 4, Pin 6 - Speedometer signal
Plug 4, Pin 7 - Tachometer ("Term. TD") signal
Plug 2, Pins 10 & 11 - nothing on these, may not have been used on GTS?

 

Thanks Tom!

Sounds very plausible, I'll buy it

Cheers!

Plug 2, pins 10 and 11 interface with the RDK tire pressure monitoring system and provide the data feed from the RDK controller to the instrument cluster.
