Tacho Wire, Urgent Help Needed Lol

[rapidmi 4]

can anyone tell me the route the tacho wire goes, ive got a coverter wired up for the turbo engine, all workde fine but i had half the dash out earlier and after putting it back in its stoped working, the side that comes out the top off the brown plug viers over towards the fusebox am sure its broken here somewhere, can anyonce help?

The wire runs via the fusebox (fuse #1) so I'd assume it runs from the coil to the fusebox & then back out to the dash via various plugs inside the car.
