I’m looking for some knowledge. I have a 2005 Tacoma. It has keyless entry but doesn’t give a short beep of the horn when it is locked like other cars. I installed a relay using the lock signal for the locks as a trigger to activate the horn. The relay functions fine except that the horn honk is too long. The trigger signal is a positive 12 VDC. Is there any cheap and easy fix that I could install to shorten the trigger time length? Thanks for any help.
