Radio-rear lights problem. 1 Year, 5 Months ago Karma: 2
Hello, I am new here and I have just bought a 1990 mr2, the previous owner said that when the radio is plugged in the rear lights fuse blows.
I have tried it and that is what happens plus the front side lights also go out.
Can anyone see the connection from the radio to the rear lights? unless there is a short circuit.

Hi, welcome to MR2.ie

Sounds like a bit of funny wiring going on there. Do you have a multi meter and are you good at troubleshooting? if so then take a look at the MR2 BGB: mr2.ie/mr2/bgb/mk2/

If not, then I'd say give an auto electrician a shout.. I can't see any reason why the radio would be connected to the rear lights.

If you're suffering from lag, you're either in the wrong gear or the wrong car!

I take it, it's an aftermarket stereo I say who ever wired it in connected into the live feed goin to your lights for the back under your Dashboard, trace it and feed it into your live for the ignition use a face tester for when you turn your ignition on and off so u know u have the rite one, sure let's hope that's all lt is and best of luck with it, keep us updated on how u get on, and welcome to the site.

Thanks for your responce. I have tried all i can, I have the full Workshop Manual and can not see any likely Connection to the light.
I have now put it in the Workshop and let them sort it out.
I will let you know what the Problem was when I get the car back.

Hi, Thanks again for your responce, it is an original Radio/Cassette with cd.
As I said I had put it into my local Workshop who have sorted it out. I tried asking what they had done but as I am in Spain I couldnt understand but the lights work and the Radio together. If it had been an after fitted Radio I could have traced the new wiring to where they had picked up the supply. But as its all working let sleeping Problems lie.
One question though when I had the Radio out, there was a yellow cable(I think) with the letters 'ILL' this was taped up, not used, anyone know what this was for.

ILL cable is for illumination
when you turn on the lights, the display on the radio should dim if it is connected up
so that it's not too bright at night and cause distraction while driving
