Help Clarity on installing BLIS to 2019 Ram Rebel 1500 DT New Body.

IF I
• Replace Driver & Passenger Mirrors to Power Mirrors with BLIS light
• Replace Rebel LED Taillights to Rebel LED Taillights with BLIS functionality
• Add BLIS Modules and heat sink to compatible Taillights
• Use AlphaODB or similar to enable Blind Spot Monitoring

…am I done? Or is there an additional step required? I’m finding conflicting information. Some have mentioned the requirement of an additional wiring harness install that runs from taillights ..under body.. and into floor well.. eventually plugging in near the driver side floor/door area. HOWEVER, when I’ve seen or read that method it is when the taillights were regular taillights from a Big Horn, or similar. In which they were upgrading to taillights that are similar to what the Rebel has stock.

Thoughts?


SUMMARY
Parts

• Driver/Passenger Power Mirrors with Blind Spot Monitoring (BLIS) Triangle
• Rebel Taillights compatible with BLIS
• BLIS Modules and Heat Sink
• AlphaODB/Similar override and software update push to enable BLIS

Do I need an additional harness from the rear taillights to the front driver floor well?
