hey whats up i have a undertail that has2 brake lights and 2 blinkers.. how can i wire it so the right blinker and right brake light both flash when the directional is on? do i need relays and stuff? any kind of diagram would help also.. thanks

 

you need to buy a trailer converter. it does exactly what you need it for its made so when a car has a different bulb for the brake and the blinker. and the trailer has one bulb for both. you can get them online or even at walmart.

 

good call but what im thinkin of for a trailor converter is usually pretty big isnt it?

 

Usually the trailer converters are pretty small. The one I have installed on my truck is about 2 X 2 (inches that is). You can cut the wire to fit your application. Becareful to leave some your self some slack in case you make mistakes and have to cut again. Good Luck!
