Has anyone installed one of these piece of wire with a little plastic so called resistoron them in their Avenger. I bought one but I hesitate to install it as it directs you to unhook the battery and I am afraid all the electronic programming (radio, handsfree phone, garage door opener, etc.) programming will be lost. Further, does it work?

 

Others here said you get what you pay for. here is a link to another thread about it. Good Luck. MC.
