Help: GATE PicoSSR 3 in a P90 (version 6) gearbox

[Gerardonimo]

Hi,

I'm trying to install a PicoSSR 3 in my P90 and I'm having trouble making sense of the wiring. Ideally I want to keep the stock battery connectors but any videos I have found to help have replaced them or been a bit too confusing. Can someone give me a better idea of what goes where?

Cheers.
