Default 98 FLSTS connector

Under the seat of my Springer is a connector that's not connected to anything.
What is it for?
Looks too many cables entering it to be for battery charging.

Doesn't seem to appear on the wiring diagram either.

Now you get to play electrical detective and trace those wires back...

It may be an accessory electrical harness that was added by a previous owner.

I’m thinking an accessory was added. But, that’s a lot of pins in that connector for an accessory.

Is there a relay in that harness? Could be a factory alarm was added.

It looks like a factory accessory harness, not for any particular accessory...

Almost looks like run, stop, turn pigtail?? But then again, maybe not? Have you probed the connector?

It's all back together at the moment.....when i take the seat off again i'll try to see where it goes and look for relays.

Looking at the standard wiring diagram, a pink wire only appears by the ignition module. Other colour wires look possibly to do with indicators?
So I suppose an alarm is possible?
My other thoughts was if the bike had a trailer at some point.......with lights and indicators?

I just had a look on line at the standard HD security system, and looking at the picture below.....if the cap comes off it may just plug into the connector I have?

I have that installed on my 1998 Ultra. The cap does not come off the TSSM. The connection is on the opposite side of the cap.

The unknown connection looks about to fit the TSSM. Also, this is the right area where it would be installed as well.

Any how…..looks like the alarm to me.

Its a Deutsch 8 way connector, it could connect to anything...

Get out your voltmeter and see what circuits it is connected to.

We could guess what it was used for until the cows come home, what`s the point?

It looks like the mating other side of the connector is plugged into that connector, being used as a cover.

Factory harness connector since is still have the factory cover cap on it, and which the bike did not come with the option that would have used it.

List of factory option, and would just look at the list to see that electrical option the bike does not have, that chances are that connector was for one of the options.

Note, look at the wiring diagram again for acc type connectors that you may have missed for the connector.
