I'm just the guy you are looking for....I bypassed my AutoRide system in 2013 and have no regrets.
There is basically no way to disconnect the Ride Control Computer (RCC) because it interfaces with the PCM, BCM, and ABS to get the data it needs to adjust shock stiffness. The fix is to wire a resistor in place of each shock absorber to fool the system into thinking there are shocks connected.
Here are the resistors you need
eBay, these are the same ones I used. You'll need to order two pairs.
When you remove the OEM shock, you will see a two-wire harness that connects to the top of the shock. Unplug that connector from the shock and cut off the factory connector. Connect the two wires to the resistor. You can use the supplied crimp connectors, or solder the connections like I did on mine. I would recommend heat shrink tubing over the entire resistor and connections to keep the weather out. Zip tie the wires out of the way so they are not flopping around and install the shock of your choice.
Once all the resistors are installed, start the truck and you should not have any "Service Ride Control" message. There is no need to disconnect the battery or reset the system, the RCC sees the resistors and thinks shocks are connected and all is well. As I said, I did this back in 2013 and have not had any ride control error messages at all.
You'll note that 3 of the OEM shocks have plastic dust shields for the piston, the RR shock has a metal one. The reason is that the exhaust routes very close to the RR shock location. I got one of these
heat shields and clamped to to the exhaust were it runs by the shock and have not had any warpage or distortion on the plastic dust cover of the new shock.
I orginally installed KYB Monomax as replacement shocks...the truck rode very firm but the handling was very controlled. Everybody recommended Bilsteins, but I was also doing a bunch of other work to the truck including brake and fuel lines, so I was watching the budget and couldn't drop the extra coin on the Bilsteins.
The KYBs needed replacing this spring and I decided to spring for the Bilsteins. I got the yellow/blue 4600's because according to Bilstein the 5100's are for lifted trucks. What a disappointment! The truck wallowed and bounced all over the road...on a bumpy road it felt like the rear axle was going to come up through the floor. Maybe pickup trucks have a different handling dynamic, maybe guys like a softer ride, I don't know. I ordered another set of KYBs and sold the Bilsteins on Craigs List, and couldn't be happier. Bear in mind this is only my opinion, you get whatever shocks you like.
Hope this helps, feel free to PM with any specific questions or if you run into issues.
