Sidecar Electrical Hook Up Issue

#1 · June 10, 2023, 11:18 am

Finally got my HD Sidecar mounted on my bike. 2001 Road King with 2001 HD factory sidecar (TLE).

Electrical issue is…

HD Sidecare wiring harness part# 70221-99 is unavailable, obsolete.

I did a dealer search for the part and searched on eBay, NO LUCK.

I think the part is like a “Y” splitter harness.

Does anyone have advice or any ideas on where I go from here?

2001 is not CANBUS so it will be a lot easier . You are going to need to make the harness.

Put a fuse between tub and tug.

2001 wiring is pretty simple. For turn signals to work right you may need a load equalize.

Custom Dynamics may still offer and adapter for the Y . Many used them to add other lights. Like adding tour pack ect.

OR.....you could call Lewis at Electrical Connection in Tennessee...... https://electricalconnection.com/

I just looked it up, and they have the Y connector you need.

Speak to Lewis, and only Lewis, as he is the owner, and theeeeee man when it comes to this stuff. Just tell him you have a 2001 Road King, and you are installing a H-D sidecar...he will understand.
