hello everyone, I'm a new member and this a my first post! And I had a very good impression of this website, really great work mates

Soo...I have an escort mk4 L 5dr 1.3 OHV pushrod engine, and its all standard including the instrument panel with a time clock.
I want to change the instrument cluster with one having a rev counter that I already bought from e bay together with a white dial kit
so now I am looking how to install it and make the tacho work
since no harness is ready for it and no other harnesses are available.
My current dash got two red plugs at the rear, and the rs got two larger blue and white plugs + then I've open both of them and I've noticed that the temp and fuel gauges aren't similar my current gauges are tightened with two screws and connected to the circuitry with them while the rs ones got three pins respectivly. The rev allso got three pins which I didn't asspected since many told me it got only a sender connection, till now its a mission impossible, any help and ideas are apriciated!

Thanks allot!
