My old bulbs we're looking trashy so I decided to put LED replacements in. Now I have the hyperflash. What is the easiest way to fix it? I see there is an electronic flasher option and a resistor option. Can anyone give a definitive answer/guide on this for dummies?
If I do the resistor route, what wire does it go on, and what type of resistor is it? There's some cheap 6 ohm ones on Amazon.

Look it up. I believe it’s an EP27 flasher at any auto part store. The idea of soldering resisters vs a plug and play flasher makes zero sense to me.
I did this to both my Marauder and my F150 and both work perfect like nothing was ever changed.

So there is a spot for the EP27 to plug in then? I was reading it only worked for 2007+ Panthers...

So, first I’ve really heard of this. Just changed those bulbs out actually with new longer life ones. I know LEDs basically last forever, but are they brighter?
What is hyperflash by the way?
Where does the flasher fit in the system? As with all upgrades, looking at the cost/benefit and how to do it.
Thanks.

The LEDs I put in are definitely brighter and more crisp color.
Hyperflash is where the vehicle thinks a bulb is out and flashes at what looks like twice the speed. Very annoying, at least to me.
No idea yet, just got under the dash and I don't see where it would go in plug and play considering there is a lighting control module involved. Looking for clarification on this. Maybe he means under the hood?

It's not plug-n-play. You will need to splice the electronic flasher into the LCM harness.
Been running one on mine for years.
I have a few made up for sale with instructions.

Cost is $25.00, no display to see.

Cool, thanks for the info. Just gets down to if it’s worth it to have brighter when the standard ones are working OK.

Sorry if I steered you wrong, I just don’t recall having to do any real kind of work under there?

On RedTube, I mean YouTube I saw this vid from Larryo340 using Mercury Montego modified LED tails and an electronic flasher. Although quite a bit more involved and more expensive it's the direction I will be taking. It looks wayyyy better than OE and performs like stock LED taillights. https://www.youtube.com/watch?v=V3QTjasHKNs

Wiring in an electronic flasher is the only way to go in my opinion. I did not like the idea of having resistors in the car which get very warm...I just don’t trust them. I put the electronic flasher near the steering column, and spliced into the multifunction switch harness instead of the LCM. The wires that are needed travel thru the switch which to me was easier then getting under the dash at the LCM harness. Using the factory wiring manual I located the wires at the switch and installed the flasher.
Side note:
I did attempt the same modification using Montgomery oem LED’s to the Marauder tail lamps, but the Marauder lamp is not as deep as the Marquis lamp causing all sorts of fitment issues so I called it quits.

I am quite sure those wires can be obtained at the body harness to rear of car in door jamb. I use Identifix so I'll be keeping notes/pics and share my experience when I do this mod. Thanks Larry for the vid!

PM me the details I'll take one. I'd like to know how it works in and the difficulty level

Need to install a Phillips CAN-Bus adapter for my front turn signal led's due to hyper flash issue. Does anyone know the wire color codes for positive and negative wires going to the turn signal socket. These adapters must be spliced in at that point.

Do you have a DMM?

I am not sure what a DMM is ? Would this be a Digital Multimeter? If so yes I do.

A resistor is the easiest way. But will still draw as much power as incandescent bulbs.
I have yet to see a decent write up for which relays need to be swapped, or what or where a multi function switch is at the steering column.
I plan to get into it this year at some point though when I try to recreate the one-touch, 3 blink turn signal thing that new cars all have.

The multifunction switch IS the turn signal stalk. On these cars (and most Fords for that matter) the brake lights go into the switch and are split left and right for the rear brake lights/turn signals. Also split for the front turn signals which DO NOT also act as brake lights. And four-way hazards. The parking light circuit does not redistribute here. The rear wires can be obtained here and extended to an electronic flasher. I believe these wires can be found at the body harness in the DKP or along the door frame under the carpet. Turn the hazards on and start probing. If you cut the wire and the corresponding light goes out you know you've found it. Use that as a splice point for the utilization of an electronic flasher.

One-touch blinker is common on a lot of vehicles now and is quite simple to achieve electronically. On some trucks the 3 blink becomes 6 in towing mode. Try this and it might be just what you need for a timer circuit https://www.amazon.com/Directed-Electronics-528T-Accessory-Pulse/dp/B0009WP09K

Yep, mine were 3 flash, I hex edited them to do 6 flashes and 9 with a trailer

Nice! I'll check it out. Thanks.
