No, it isn't.
May try a search for "amber turn signals", search by message text and in the archives.
Basically, what is involved is cutting the wire from your brake light switch before it enters the GEM and combines with the turn signal signal wire(s). You then run a length of wire from the cut brake light switch, from the switch end, to the driver's side rear light. At the lights you cut the MAJOR wire (marked on the connector) on the current brake/turn/tail light. Connect the wire you ran to the cut MAJOR wire, connector side. You then cut the signal wire at the reverse light and connect the harness side of the MAJOR wire to the connector side of the reverse light. Next, you do the same thing to the passenger side, using a bit of wire spliced into the wire you ran from the brake switch.
What you are doing is removing the dual function of the MAJOR signal wire and only retaining the turn signal function on the MAJOR wire. Since you no longer have a brake signal wire, you have to run a new wire for brake lights.
To retain reverse lights, run a wire from the harness side of the cut wire that did run to the hot side of your old reverse light to auxiliary lights mounted wherever you wish.
It takes a bit of time to do, mostly spend hiding your ran wire to make the conversion look neat and tidy.
