I had actually completed my nitrous a long time ago. Ive got the bottle on the transmission well between the driver and passenger seat so I didnt have to buy a remote opener and it looks really cool honestly.
I was able to do it myself and the only weird thing that came up was some extra blue wire that was on the relay that didnt seem to go to anything. I called nitrous express to see what it was about and for me I did not need it, I forget what the actual use for it was since it was not in the physical instructions. Due to the yearly heat I keep the Nos bottle in my freezer. Ive yet to install a purge kit because I sort of like the idea of guaranteeing the fuel sprays into the engine before the Nos does. The fuel system is getting its fuel from the fuel return line behind the engine.
