Hi, which wire do i need in the engine room to connect to my aftermarkter rpm gauge (rev counter) ??? (the gauge needs a negative input)

It is a Ford Fiesta 1.6 turbo from 1991 ... thanks in advance!!!

Cheers

 

Either the coil wire will work if you can choose "2 cylinders" in the gauge. If not, you can try the CTO "clean tach out" which is pin 11 from the EDIS unit. This works fine at least in my escort using the original S1 clocks.

 

okeej, i connected to the coil wire (one of the green ones, seems both work) but chosen "4 cylinders"... it worked but not as it seems, so will try to change this to 2 cylinders..... thanks mate

 

won't work... i can only set up for 4, 6 or 3 cylinders

is it surely wire 11 (on the picture the arrow shows wire 10)



thanks

 

Pin 11 from the EDIS unit. That looks more like the instrument cluster connector or something.

 

Sorry to but in, but JesseT, on the FRST ECU is there a digital rev counter outputthat you know of? Preferably 5 volts, its for my HKS Turbo Timer

 

I have no idea of the ecu itself.

 

Oh ok it was worth asking though
