Dear friends
For whoever is on this same situation with a non working 1sec timed relay, here I found for Mr. brandini a solution built on HELLA timed relays.
The relay should be bought and sent to me at any circumstance since there are different models, and not all, even looking exactly the same do the same thing.
There are DELAYED ON relays, DELAYED OFF, etc.
Look at the picture with the solution. Harness for 120$ plus shipping. The relay cost about 65$ plus freight and taxes.
Best regards
