i must be the biggest tard around these days so i apologize in advance.. i am trying to install an interface that allows me to use my stereo hand controls for an after market radio. in order to do the install i need to find the radio remote control switch. By the shitty directions it says it may be located in the stearing wheel column. How can i remove the casings around the key cylinder? or has anyone messed with something like this before and know a better way? thanks for your time.
