For a standard 4-pole wiring harness with taillight converter we offer many options such as # 119250KIT. This is powered converter that requires a 12V power input from the vehicle battery in order to operate. It takes in separate stop and turn light signals from the RV and combines the stop/turn lights into one circuit.
On the 4-pole output side the green and yellow wires will then carry combined stop/turn signals for the right and left trailer lights. The running light (or clearance light) signal from the RV is also passed through on the brown output wire without being changed.
This kit is a hardwired type that that connects without splicing into the vehicle taillight wiring to gain access to these various signals. The kit includes a circuit tester to make it easier to find out which vehicle wire does what.
The wire connections to be made include connection the red wire to the brake light circuit; the green wire to the right turn; the yellow wire to the left turn; and the brown wire to the running/clearance light circuit.
I have linked the written instructions, a helpful article on trailer wiring and an installation video to give you as much information as possible.
