I have a 1978 Cobra, 302, auto. I bought the car in rough condition and have been working to get it back on the road. I rebuilt the 302 and I’m having trouble with a few things, one being the tachometer that doesn’t work.
The cluster printed circuit board has the part number that starts with D4ZF. However the tachometer adapter has the part number D7ZF. The tachometer itself has the part number D5ZF.
I bought another complete cluster that has a printed board of D5ZF with a tachometer with part number D7ZF and the adapter / D7ZF.
It still doesn’t work. Does it matter that the printed board is a D5ZF or D4ZF?
Any ideas as to what is wrong? All the wiring looks stock.
The fuse box is so worn? I can’t read what some are supposed to be for. How many fuses deal with the tachometer?
Thank you.
