More than likely you will need the load equalizer.... it's plug and play. I tried mine without it and they blinked fast. I ended up calling their tech support line and they walked me through it. Their customer service is awesome and so is their tech support. You might also have to relearn the control module which is simple but I don't remember the exact sequence but it's something like this: turn the ignition on, press the L signal, let it blink twice then press the R signal and let it blink twice, continue this alternating sides for maybe 10 times and it relearns the control module. Again, tech support will walk you through it.
I'd give them a call and they can tell you exactly what you'll need. the entire team is very knowledgable of their products!
Good luck..they'll work!
