00-02 wiring help

[Yukongk]

When I installed my aftermarket head unit, I used the supplied adapter harness from Crutchfield. It had a blue remote turn on wire that I spliced the head units blue turn on wire into. Most people splice into the pink wire on the on star harness. The factory amp has always worked fine like this, but I recently found a 400ma parasitic draw from the factory amp (pulling the RDO amp fuse under the hood drops me down to a normal 50ma). Does anyone know if connecting to the pink wire would make a difference and shut the factory amp off when the radio turns off?
Thanks

The blue remote wire is IGN power to remote power-on AFTERMARKET devices (amps, power antennae, sound processors, etc.. ) when the head unit turns on. If you are just replacing the head-unit and only the head-unit, tape off the wire and do not splice it anywhere.

I have the same drain issue w/ the RDO amp fuse. Is not the amp supposed to shut down when the truck is turned off? I'm currently pulling that fuse every evening and plugging it back in in the morning. Getting old. Any suggestions?

Yes. My suggestion is to do as I am and order this:

I don't want a new amp - I just want the one I have to not drain my battery.

FWIW yesterday when I parked it I turned the radio off before turning the truck off, and this afternoon it cranked right up. That's either the solution or an acceptable work-around.

Don't know what to tell you, I don't know of a fix.

Best way to check if you solved your problem is with an ammeter in series with a battery cable to test the electrical draw.
