Anyone have detailed instructions on how to install these hand controls? I'll gladly pay someone to scan/copy and send to me. Mine are about 20 years old but still as good as new, unfortunately all the mobility places near me said they won't install/swap them from my current car to my 2005 Caravan because they don't have the new accelerator lock safety feature. Thinking of just finding a mechanic who will do it but want to be able to give them instructions.
