I was planning to use a piggyback to get switched power from my fuse box to my gauges, but every fuse I checked had power to it with the key off. What next?

 

It is a little more work, but I run all my stuff from a relay that is triggered by the fuel pump wire under the hood.

 

I thought about that too, but I also need power to my LC-1 Wideband and it had a blurb in the intstructions that the trigger should be deactivated during startup (like and AC system is) so that it won't see the spike in current that the startup will cause.

 

I also have a relay activated by the fuel pump wire for all my accessories. I've been running my LC-1 off of it for almost 2 years with no problems.

 

I also have an LC-1 wired off that relay. No problems yet. Are there any relays out there that have a few second delay once triggered?

 

I haven't found one.

 

Nelson recommends using one of the pink wires under the dash that hot when the Key-on.

 

any pink wire under the dash, or are there specific wires?

 

Yes any pink wire that has 12v power with the key on

 

Yep i would use the pink wires, i have my amp wired to the orange ignition wire so its only on when the truck is running which is nice.
so pink to be on with all accesories
or orange for only when truck is running
oh and they are under the steering column and not too hard to get to
