ok so i got the unit all wired in perfect.
issue is, last track day i had a small fire which touched my wiring loom that goes to headlights, p/s, afm (so turbo side)
since then my tacho hasnt worked.
we tried to fix the dry solders on the back of the tacho, still no work.
just bought a new WORKING cluster, fitted it up and still no working.
have has consult connected and that said there was nothing wrong.
what could be the issue?
