We just connected the new engine and light harness from M&H. The Horn relay is new and it buzzes until we disconnect the horn. If we push the horn button the buzzing stops also. Any Ideas on what this could be???
Sounds (small joke) like the key minder circuit. Car is acting like you left the key in the ignition. There are contacts by the ignition key tumbler that work when the key is in. This switch, along with the left door switch and relay make up the circuit.
