One of the plugs connects to another plug near the main plug and sends power to two other aux plugs. One in the main cabin and one on the rear part of the frame.
Unfortunately it's different underneath. There's a hard plastic piece instead of the foam like in the 3rd gen. Pretty annoying. I'm 6'5" and barely fit. I noticed that as the day goes on I fit a little better, lol. I bought the tacoma later in the day so I didn't notice the headroom as much.
Thank you so much for posting this fix. I was having the same issue. I did exactly what you did and now there's no vibration at all. I thought my rearview mirror would fall off because it was vibrating so much before.
Does anybody notice a little clatter sound sometimes when in lower RPMS and usually somewhere between 2nd and 4th gear upon medium to hard acceleration? It shifts perfect and is smooth, but almost sounds like a knock or something. I thinking its just heavier load at a lower rpm like most cars...
Great write up. I just removed my rock rails and was wondering if before you installed yours, was there anything in the bolt holes in the frame that you needed to remove? Or was it just a threaded hole in the frame? I'm just wondering if i need to plug the holes. Thanks.
