Does any one know which pins where to apply +12 and ground on the NTG2.5 from an external power supply to test unit powers up before I buy

Thanks

Although not a complete answer as I don't know the pin numbers ...

You can plug it into a NTG2 car (A/B/W203-C/CLK/ML/GL/R)

Do not plug it into a NTG1 car (E/CLS/SLK) without an adapter loom

If you look at this picture, brown is ground, red is +12 (the wires roughly in middle of the picture)

thanks for the pic but that plug looks like the wrong one to go in the back of the unit im looking at it has 16 pins on the back, it will be replacing a audio 20in a SLK

That is definely the main NTG2.5 power connector. Whats the part number of the unit you are looking at ...

The part number of my unit is A 171 870 47 94 model BZ9860

That is an Audio 50 APS without CD changer. I havent actually seen one of those - can you post a picture of the back of the unit please ?

Thanks
