Hello everyone I did not find any info on this topic. So i just started and made some pictures. I hope that its useful info. You might have some tips. First pic shows how to splice the loom with a small pair of nail siccors.
Then take the old ypvs wires out. And use the old dc connection from the ypvs. This is done by lengting the brown cable to the igni. I raised the fuse from 5A to 10A.
I made a new bracket from alu for the igni.
For the ypvs i made a sub loom with the old connector. Soldering the wires and wrap some fulcanising tape. I will finish this with black insulating sticky tape.
Next job is to make the other connections for dc killswitch and pickup. I gave every wire that will be used a tag nr with papertape.
