Weird wiring

[RoddQLD]

I installed an Alpine stereo in my 1997 80 series. I used a new adaptor to attach to the original car loom (so no cutting, etc).
Stereo works 100% BUT I now have a problem; when I press the brake pedal the ashtray light and the side lamps light up!

I doubt whether simply connecting a stereo would cause this problem but I may have inadvertantly done something else.

I will be looking at the wiring diagrams and check the work that I have done, but I'm hoping that someone here may already have an answer.

BTW; the work was correctly done following the colour codes for the Alpine radio and the colour codes for the new loom connector. The joins between the new connectors leads and the radio connector leads were soldered and have had heatshrink tubing put on them.

Any prompt help would be greatly appreciated.

Gday
Ashtray and side lamps (parkers) only?
What happens if you unplug the stereo?

Actually, I get the same result as if I had turned the 'parkers' on (even the digital clock dims!).

I just had a look in my Max ellery's workshop manual wiring diagram and the wiring to the stop light, cigarette lighter, clock, etc runs via the 'power junction box'. If this refers to the power connection point in the engine compartment then I certainly worked on that item. I ran the 3 power circuits (+ve, via ign, via accessories) and earth using a 4 core multicore cable to behind the radio (for my Uhf radio).
I'll have a look at the 'Power Junction Box' tomorrow.

Problem solved.
It was simply a coincidence that threw me off.
I searched this forum and came across a post by Kenton in Nov, 2004.
He said that his brake and tail lights were operating as one. For him it turned out to be a short inside the brake/tailight globe. Just happens that it also activates the dash lights and dims the digital clock!!!

My problem appears to have been caused by a short between the stop and tail-lights in the trailer plug.

It's just a coincidence that this has happened at the same time that I had installed the stereo system. Sheeesh!

Thanks for your interest fellas.
