LOLWell, its been around 5 months now since I disconnected the cable leading to the high level brake light as it was stuck on all the time.
I never could find that elusive diode even after stripping down all the front loom tape
- I did find the water damaged connector that fed the HK amp - FIXED OK
Ive just had the MoT & was informed beforehand by the testers that High level Brake lights MUST work if they are fitted - so I reconnecected the cable & 'VOILA' - it all seems to work Ok for now - must have been that bug that gets into the BC1 from time to time !!
