Hey,

I wanted to know if this is possible/correct/safe to do.

I currently have one relay being "activated/triggered" by a switched power source from the interior fuse panel. I used an "add-a-fuse" to the wiper fuse. That wire goes to 86 on the relay.

I now need to activate/trigger two more relays, would I be able to activate my other two relays from that one fuse? I was thinking of twisting three wires and soldering it to the tapped fuse, each wire from the tapped fuse would go to a separate #86 pin on the relay.

I used my test light and couldn't really find any other non-important switched fuses.

Thanks

Edit: below is a picture of what I am trying to do...
Each relay has it's own ground, and lead from battery, just want to know if I can have a shared switched source or does each relay need to have it's own switched source

Do you have a sunroof?

I do not but my fuse box had the pins for the fuse.
That is the circuit I used as a switch source to power my AUX fuse panel for the things I add to the car.

No sunroof, also tried that fuse slot just for the heck of it and the fuse doesn't stay in... just falls out lol

It depends on your current draw. If your just using it to power the relays your fine. However if you start using it for the main power source of a amplifier or a beefy compressor you e will have problems

Just to power the relays, for my main power source I ran some wire from the battery in the trunk. I believe the relays themselves draw very little current...

Just out of curiosity you don't know the max number of relays I could be able to use?

relays dont use that much current but then again they do. how many relays are you talking about here?

Hey,
Sorry for the late response, but I would like to follow up on this thread.

Emp I am using the wiper fuse to trigger three relays at the moment, it's been about two weeks and haven't had any problems thus far.

you should be fine 3 relays isnt too bad. especially in FL since you probably wont have the wipers running full speed for an extended period of time
