LED turn signal hyper flash problem
I swapped out my stock incandescent turn signal bulbs for LED's in my 2005 F150, now I have the typical "hyper" flash so I bought LED load equalisers.
My brother (master mechanic with 5 ASE certifications) tells me I really didn't need the load equalisers, Ford thoughtfully provided a factory LED wire under the dash I can either ground or power (he couldn't remember which) to correct the LED impedance problem.
Problem is now, I'm just too damned big (and at 55, too old in inflexible) to fit under my dash to look for the right wire, can anyone give a heads up as to where I should look and for what I should look?

LED signal lights were never available for any F-series in '05, so Ford had no reason to put an "LED wire" there. You need a new flasher module, as GLC and SHO89 explained. Maybe your brother was thinking about a different model year, but I can't imagine how grounding or powering an additional wire is going to change the resistance/impedance of the turn signal to fool the flasher module.

Anyway, went out and got a new EP-27 flasher module, we'll see if it works, when I install it after all this DAMNED rain stops!!!
Also gonna take back the load equalisers and get my money back
Last thing, I've checked under the driver side dash/kick panel, the passenger side dash/kick panel, under the hood, WHERE THE HELL does this flasher fit?!?!?

Do this ^^^ (or just turn on the 4-ways). It's up under the dash near the steering column.
2008 was the last year for the flasher relays in the F150, then it went to being integrated into the SJB (aka BCM). It was still controlled in that module through 2013 MY, the extent of my F150 tech library. I don't know it it ever went to being controlled by the PCM after that, don't have those diagrams.

Sure makes it hard to be a shade tree mechanic, but, I DO like the fine control those things supply.
