Any recommendation on a good power distribution for a 77 shovel with turn signals? Ideally I just need the relays and I can wire the rest myself, would be helpful to have people's opinion as I am new to this.

I've looked at these so far:

One other one to consider for you:

It's not a complete harness, but rather a solid state control box that simplifies the wiring immensely. Specs are great, and includes an alarm as well.

I am seriously considering this for my '80 FXWG build. It deals with all the relay, flasher and fuse functions. Actually, I lie - I have decided to use one, just haven't bought it yet as the bike's not ready for it.

There are some good videos about it from Revival Cycles on YouTube.

It's pricey - but looks like it's an excellent solution if you are comfortable with basic electrics and running the wiring yourself.

 

Have a Badlands relay module in my custom sporty small fit under seat runs all lights turns markers brake also great with LEDs

 

Stay away from the Thunderheart stuff had a of lot past experience with their crap it has a high failure rate . Ultima is decent and will be more common.
