Does anyone know if the tachos from XF clusters are the same spec as EA? I picked one up from the wreckers yesterday, as it was lying on a back seat by itself and got it for $13, but when i try and run it in my EA 3.9CFI as a top-of-dash mounted tacho, it reads about 400rpm or so higher upright (normal position) than when flat. The flat reading seems more correct too (dad's tacho is dead, so i can't check it).
i'm wondering if the tacho is different or if the coil is putting out a different voltage or something. Also, I've read here that redline is about 5500 rpm, but I ran the tach today on Maroondah hwy and I backed off the throttle at a reading of about 3800 rpm as it sounded a bit scary... i'm thinking it was closer to 5 than 4...
if it is an aftermarket tacho, ie not a ford factory one then it should just work. all u need is ground +12 and a tacho signal. also check to see if it has a switch on the back of it to select if it is a 4 - 6 or 8 cylinder car

hey EDXR6 you seem to know your stuff.
Was wondering if you could help me here (or anybody in the know)
I just brought an after market tacho (3 3/4", before you call me a "RiceBoy" the bloke at my wreckers quoted me $140 for an ea s pak cluster, and the tacho was only $98) and it has four wires:
but there's 2 I'm unsure of, one of them being the tacho lighting and the other being tacho signal, from my understanding it's a pink wire, you have an ED so I thought i'd ask you where it is.
Help would be GREATLY appreciated.
