Default 1999 Fatboy - Where is the turn signal module?

Sorry for the perhaps seemingly stupid question. I don't own this bike, so I can't go out and simply look. As it is, I've been all over the internet attempting do 'search' this question....... but everything I find is all related to either 'relocation' of turn signals......or newer bikes.

My friend has a '99 Fatboy and has been having the problem of having to push the turn signal button multiple times in order to get a T/S to work....either side. Seems the module is what would otherwise be a 'flasher'....... but I'm unsure. Does the bike have both a standard flasher AND some kind of canceling module? And, if so, where are they located? I can't even find a picture that comes close.

Any help would be appreciated.

Thanks,

WC

The "MODULE TURN SIGNAL CANCELLER" is a module very roughly the size of a pack of cigarettes, which turns the flashers on when the switch is pressed, makes them flash while on and turns them off when pressed again, but also has a time and distance feature that turns them off automatically if they are left on for a while.

Precisely where it is on a FB I don't know, but the place to ask is in the Softail section. If the chaps in there don't know then there is no hope for mankind!

It is mounted to the top of the frame tube, between the fuel tanks.

Ive been told by a friend thats currently mechanic at my local harley davidson shop that its located underneath the rear fender somewhere. I havent had a chance to fool with it yet but I will give update when I know 100%... I do know that the OEM replacement cost $145. here in TN they have one in stock thats been on the shelf since 2006 lol must not be a common problem,or there isnt any of us old EVO ridders left out there to justify service lol
My 99 fatboy just started acting up with the signals not wanting to flash ,I have to constantly tap the direction switch so my signal appears to work proper unless your paying attention to light flash timing "gets a little off rhythm when alcohol is added" hiccup.. Ive been told by the pro non redneck jerry riggers like myself not to bypass and run it old school since the damn thing controls all the other modern bullshit,most importantly it shuts down the scooter if you were to crash and its ontop of you and if you bypass she might not run at all.
Any of the old heads have any suggestions?? Personally I would like to run it old school but I worry without the module linking with the computer that it wont even let the bike start/run.

Newer Softails are by the swing arm in front of the tire and are a TSM or TSSM. They can shut down the bike. Your friends is a 68540-96 and it's just signal control. I'm pretty sure I have one in the garage. There's also a bunch on Ebay. PM me if interested.

HOWEVER - it has separate in signal pins for right and left from the switches. Your buddy should be checking the function of his switches before replacing parts.

The lower mud guard on the rear fender removes with 2 bolts behind that is where the TSM is located.
