Hy Guys!

I'm a new member and to greet everybody!
I have a great problem, please help me, if you can. I have an escort MKIV 1.6i CL estate. Intermittent wiper switch (with 6 speed rotary dial) doesn't in my car, only the normal switch with 1 speed without rotary dial, because my car doesn't ghia, but I like very much the 6 speed. I have bought a 6 speed wiper switch. Number: 89 AG 17K 478 BA
and a new red relay with 5 legs(the normal relay has four legs, without the middle "P" leg) Number: 78GG 17C 499 BA

I know, that this function was factory extra for example in escort MKIV ghia in 89-90, in the spec 90 series, or in orion ghia MKII. This relay is third what I bought in the last year. One was working approx 2 hour, and it stopped, without a trace( no smelling, no burning, I don't see anything on it, neither either nor outside, the solder joints are intact) I bought the other in the last week.When I connected and started, it was working perfectly, than when I try to start after an hour, it didn't work and it doesn't work since then.
My method was the next: I connected the point 54 of the wiper switch (this leg belongs to the diary Knob, and this leg is the single, what misses from the normal switch)with the middle "P" leg of the relay with a wire. Do you think, is it good?
I daren' connect the new relay. What would be the fail?
I don't find a car in Hungary what I would check, I can't check the wire from the switch to the relay. I think that should be any little control electronics on the wire between the switch and relay, but I dont't find any information or picture on the internet.

I don't now what to do, therefore I turn to you now.
If anybody has such a wiper switch in his car, please help me. If we were able to follow the wire, perhaps we should to solve my problem.

I attached the pictures of interval switch and the relay.

I'm waiting your help here or in private message.

Thank you very much.
