I bought a used Leer cap/topper, and want to connect the 3rd brake light on the cap. I tried splicing into the factory 4 pin wiring harness. Typically, the 4 pin factory wiring harness is: green wire is the STOP & Right signal, yellow wire is STOP and Left signal, brown is tail lights, and white is ground. The 3rd brake light on the cap has two wires, a ground and hot.
I connected the cap 3rd brake light hot wire to the green and yellow on the four pin harness, and the brake light ground wire to the white. The 3rd brake light functions, but when the right turn signal is activated, the brake light flashes. When the left signal is activated the brake light does not flash. Any suggestions?
