Hello,
Been trying to install a relay and fusebox in the boot of my Celica (Gen7 if you care!).
I have installed as the attached picture shows. However It seems that power is going to the fusebox whether the signal line (86->85) is sitting at 12v or not. The line from the interior fusebox seems to work as expected (VAcc off= no led, VAcc on= lit LED). However whether or not the LED is lit power gets to the fusebox- I've ran an amplifier off the the fusebox (along with the signal line for the amplifier) and I still get sound through the amp at all times.
Do I need something on 87a? Do I have this hooked completly wrong? Do I have a dodgy relay?
(oh and sorry for the slightly weird depiction of ground- sure you know what I mean)
