I don't consider myself very handy when it comes to working on cars because I haven't done much of it. My Jeep for some reason is inspiring me to want to try to change that.
I decided to tackle installing a VIAIR ADA system on my JKU and the wife's JKU. She made me promise to do mine first incase I screwed up badly. I was very cautious when doing the install on mine and I spent a few evenings working on it. The instructions that came with the ADA are not good as they lack a lot of critical detail (at least for a guy like me). I found some useful help on this forum and called Travis at OBA a few times when I was stuck. Both Travis and all of you guys were very helpful and I'm grateful.
I decided while doing the install I would document what I was doing so I could share it with everyone since I was unable to find a detailed install thread using the search. My intent was to be very detailed in what I was documenting but as it turns out I failed and didn't do much more than take pictures. I wanted to list the tools and such but I didn't write them down and I don't recall all the sizes.
So if anyone wants to add to this or correct me please feel free. I'm new at doing this sort of thing and I'm sure there is great information I'm lacking.
The unit I'm installing here is this: VIAIR ADA 07-11 Jeep JK System 40041 - Onboard-Air.com
Threads on this forum that were of real help and contain more info that what is recorded here are:
Disconnect the Battery
Take the two bolts out of the brake booster
Install the bracket that will hold the compressor by attaching it where you just removed the two brake booster bolts
Notice that the one brake line may touch the bracket. It seems that on some Jeeps they touch and on others they don't. You can bend the brake lines a bit if needed so they don't touch. Others have also zip tied them or put rubber on them to protect them when they do rub
Now for the hardest part of installing the compressor. Mounting it to the bracket. Travis said the compressor can be installed on the bracket before it is bolted to the brake booster. I tried this and I could not see how to positon the bracket with the compressor on it and decided to go the route of installing the compressor after the bracket was on. I didn't get any pictures of this because both of my hands were tied up as well as my neighbors hands who came over to help me with this step. In the end what I found the easiest was coating the washers and nuts in Vaseline so that I could stick them on the bolts and take my hand away to grab tools and so on. My hand was small enough for me to slide it under the bracket from the left to do this.
Now it is time to run the wires through the firewall. Remove the rubber plug and poke a hole in it. Push the wires through the plug and feed them (one at a time so you know what is what when you connect them to the switch) into the floorboard of the drivers side footwell.
Remove the side dash panel
Drill a hold in the dash and install the button. Notice the position of the gold prong on the button. The instructions don't say it but the ground must be run off of the gold prong.
Fish the wires to the button. Be aware of what you are running them by. I wrapped both of them around my clutch and didn't realize it until I took a second look. Power (from the battery) goes to the center prong. The ground goes to the gold prong. The Delphi connector goes to the remaining prong.
Connect the ground coming off the switch to a bolt in the footwell and put the side dash pannel you took off back on.
Connect the ground coming off the Delphi connector to the bolt in the engine bay and connect the Delphi connector to the compressor.
Route and secure (I used zip ties) the wires in the engine bay.
