radio problems

[Spoony]

hi

i wanted to fit a new radio to my supra.

there was a plug going to the oem plug (white) which has to be connected to the radio. all speakers minus cables together and the plus cables speratly. the same with orange, red black and blue.

 

did everything like it was before and my new radio is working 100%.

it doesnt even start, when i usw the cig lighter + and - it starts but no sound.

if i use an external speaker it also works but none of these oem cables.

 

is there a special fuse for the radio? i only have seen that its connected with the dash light, and this is working 100%

 

does anyone have the cables route? or the colour of them??

its an 94 tt eu spec

 

thanks
