528T, keep power on few seconds

Hey Im using my 528T to keep power on for few extra seconds afer the ign is turned off. I have a external DVD/TV Tuner in my Magnum on my AVIC Z2 mainly for TV use. Well when I cut my car off and leave the ign on while in park. The tv will turn back off I have to go threw the whole process of getting back to tv again and its a pain. I used the 528T to keep power to it while the cars goes off then on and was working great in my old car. Now I cant seem to get the crazy thing to work rite. Please tell me if I have it wired correctly, I need power to stay on after ign is off. rite now I have it like this. Red 12v Black Ground BLACK/ white ign wire to TV Yellow to 12v brown   not sure orange not sure no matter what combination I put brown and orange I cant get it to stay on. It will either stay constantly or not come on at all. I think its bad do I need to buy a new one, this is so crazy.

Also is there a way to test if it is still good or not?

There's a loop on the 528, cut it and feed an ign or acc to the BLACK/ white, feed TV off yellow, join brown to the red 12v+ perm and ground black. RTFM!

RTFM well TFM does not explain my problem. why would I put the tv on yellow if yellow is common?

Yellow is the 528 output + terminal 30, brown is input 87, Orange not used is 87a, black white will give a pos feed if loop is cut thus yellow feeds your TV RTF manual that comes with 28.

Well I tried both ways mentioned above and Im not getting any clicking from the relay or any thing now. Im going to order another, I have worked with these before and have always been able to figure it out in 10 min or less.

If i were you I would take the piece out and bench test it.  See if actually is giving outputs or not.
