Ive had a problem with water running behind the fuse box in the passenger footwell.

on removal of the dash, Iíve noticed the two thin black wires from the immobiliser have corroded through. The back of the fuse board has a similarly corroded bottom plug behind the interior light fuse. Is this where the 2 wires would have been plugged in?

Any diagrams for fuseboard/immobiliser wiring would be gratefully received or a nod in the right direction. I was hoping to wire a fuse holder to bypass the fuseboard at the interior light fuse&30A Renault badge fuse. Possible? Or replace the whole loom with fusebox, immobiliser, ecu etc...
