Rear light unit not ok

And: searched further for a new or used replacement of GU06740900 - not a chance, even found search ads.

Thanks for your support, beetle!

I was lucky to have found a (non working) replacement rear light unit on ebay which I need to replace the cracked red plastic lens on my GRiSO. Taking the bloody thing apart is going to be a challenge, somebody mentioned heating it in the oven to softer the glue/mastich?. What temp? I have to be very careful this part is like gold dusk, unavailable anywhere.

One question: where is the front stop light switch located? (Number 20 on the wire diagram).

Many thanks

Dear by, I just used Heat Gun and patience - about 180 degrees and sticking small screwdrivers into openings once it is possible… And yes, patience!
