The directions are extremely simple, and installation is even simpler. Works so much smoother then the original linkage. I installed a NP231 on my 97 Zj and installed this shifter linkage cause the original was junked. Took me 10 min to remove the original zj linkage and 3 minutes to install this one. Thank you for a great product. I will be purchasing more zj items from you. A+++
