Hello, I have a client with a 2019 Mazda 3 (base) with AUTO on the AC controller. Your site suggests EVO-ONE-MAZ5 system. I intend to add the optional RFK942 kit. My confusion is with the 15 exposed wires that come from the white connector and the single wire from the harness which is labeled, “HORN”. The orange/black “HORN” wire is spliced into the white connector which connects to the vehicles BCM “B” connector. The harness 20-pin white connector has a orange/black wire which is also for the horn (-). I have the following questions:
<!--[if !supportLists]-->· <!--[endif]-->The instructions mention to connect the orange/black wire from the 20-pin white connector to the BCM plug “B” horn wire. Q: Would I simply connect the 20-pin white connector orange/black wire to the wire labeled “HORN”?
<!--[if !supportLists]-->· <!--[endif]-->Can you please clarify the HORN wiring to me, please? I ask this because the EVO-ONE has no other horn outputs and I don’t see how the horn chirps with using the RFK kit or valet switch when programming.
<!--[if !supportLists]-->· <!--[endif]-->There are 20 wires from the 20-pin white connector, of those, 15 are exposed, of those 15, one is used for a hood switch titled “HOOD (-)”, and the other one I mentioned, “HORN (-)”. Q: Of the additional 13 wires exposed on the MAZ5 harness, are these to be wired to the vehicles electrical systems or are these optional?
Thank you in advance
