Hi Everyone I'm new to this website but it's really cool to see that Panther Platform owners have a corner of the internet all to themselves. I am writing this post just to help anyone that ran into the same issue that I did and since I already fixed it I wanted to post it for anyone browsing for solutions. I recently upgraded to all LED lights for my 2011 CVPI
and encountered the notorious hyper-flash. I decided to just bypass the LCM and wire in a LED Compatible Relay. The job took around 2 hours to do it right and the hardest part was honestly just the space constraint. All the wires are easy to access and mess with. Keep in mind this was done on a 2011 CVPI
and I cannot guarantee that these instructions or pictures will match what your vehicle might have installed from the factory.
To bypass the LCM, you will need to cut the factory harness and splice in some wire and wire in a new LED Compatible
Relay. MAKE SURE IT SAYS LED COMPATIBLE OR ELSE IT WILL NOT WORK!
Locate the black plug in the back of the LCM. The LCM is a black rectangular box located on top of the OBDII Port.

. On my particular vehicle, there were 2 Light Blue and 2 White with red stripe wires.
As with everything regarding wiring, make sure you test everything before making anything permanent. I used a cut piece of wire to bridge the pins on the connector to absolutely make sure I had the right ones before I cut into the wiring harness.
Once you find those wires, you cut them and make sure you leave enough wire to be able to use. In my case, since I have 2 light blue and 2 white with reds, I joined the matching wires together and created a single wire. Notice how in the picture the 4 red wires that I added turn into only 2.
Now that you have done that, go ahead and connect the relay. The relay that I used was the Sylvania Novita EP36 that I sourced from AutoZone. It's a generic relay that is found in the electrical aisle where all the light bulbs are at. I used a 3 prong relay that required a prong but if you are able to find a 2 prong relay that works too. Since I used a 3 prong relay, I grounded the relay to the bracket that holds the OBDII port.
Once that's all done, test out the relay and mount it however you would like. I like things simple, so all I used to mount it was some zip ties.
If everything was done correctly, you should have some nice turn signals with no hyper flash and without the need for resistors! Just make sure you check your bulbs every once in a while because since you bypassed the LCM, you will no longer have the bulb-out detection
