hey, needing to know what the speedo wire colour is out the back of the dash, and if it keeps that colour all the way to the gear box... i was just cruising a few nights ago and the speedo just dropped to 0km/h, i tried changing dash cluster and also pulling off the gear in the gear box, no luck, gear still looks good and wire under the car is well insulated still... looks like i have a burnt out wire under the dash, just need to know which one it is...

sorry forgot to mention, its a ford falcon xd 81 model, was originally a 250, now a 351.
