Want to install my wheelen strobo but don't know how...
 

Somebody please tell me how to connect my wheelen strobo and sirene to my '08 ulTRa Classic main harness...?? and if it's possible..can I get its wiring...Thanks !!!

you can hook up a whelen strobe and siren to anything with 12volts.

In the spirit of Christmas, send me your email address or a fax # and I'll send you the wiring diagrams from my '04 HD Police Service Manual Supplement. Alternatively, stop by your HD store's service department and take a look at their copy for your model year.

Your problem with the siren will be wiring a switch to turn it on/off. Not hard, just different than the HD police model wiring.

The strobe isn't going to work without a 120 volt power supply (squadfitters.com sells an inexpensive one for a strobe headlight).

Presumably, you are removing the fairing lowers for the siren install???? At least on one side????

Good luck with your project.
