84FS460 Posted April 15 Share Posted April 15 I've been wanting to install a remote key lock in my 86 F250 and its already got the power locks. In addition to the aftermarket module will I need to wire in a relay or two? I've read a previous thread discussing this subject but just need to know if it's critical to install them and how to wire them in. The instruction manual isn't very helpful.

Gary Lewis Posted April 15 Share Posted April 15 I installed a Code Alarm ca1155e alarm system that does the door lock/unlocking and explained how I did it here. And yes, you will need to install relays if your system doesn't have them built in. Link to comment Share on other sites More sharing options...
