Hello all. Here is the old school way to convert your trailer wiring from the harness in the trunk by the spare (10 pin "3 wire system") to a common 2 wire system. This allows you to use the standard 4 pin trailer plug, with NO faults showing up on the SID/computer, and also allows full bulb brightness. If you have any questions, or a different plug/model, please message me, I'll see if I can help.

Stay safe out there, car love.
