TR2/3/3A Single brake light modifcation

[mallard]

My positive ground 56 tr3 only has the center brake light. I would like to make it so the outer lamps also light up. Does anybody know of a link that would provide this information on how to do it? I'm not good at figuring out relays and other sorts of wiring issues so it must have all the details and parts needed. Thanks Keith

Here's a couple of ideas.

Not too detailed, but you can always ask if something isn't clear. I mounted both relays and both resistors on a little bracket I made, and bolted that to the back of the pedal box where no one can see it (and I didn't have to make a new hole).

Thank you for the information Randall. I'll take a look.
