Phil - yes, I did completely by-pass the ERA sockets and wired in auxilliary 1157 sockets without success.
Went for a a short drive today and noticed my charge light was on. Apparently blew the #4 fuse when I turned on my signals. Tried it again at home and as soon as I hit the signal fuse blows. So - now I do have a turn signal problem to sort out. Back to the wiring diagram and tracing stuff.
