The lights in the cuda were disconnected and I didn't feel like tracing that day to find the proper place to hook up, so I simply found switched power and hooked em in. They are working great, still kinda dim, but I think that is the very nature of the E's. I will prolly replace the standard bulbs and go with LED's and see if they are brighter. I put LED's in the taillights and they are BRIGHT!
