The 528t doesn't have enough power for my aplication. How can i wire it so that it retains power for the trigger wire on my relay that controls my power inverter. I don't want the power inverter shut down right away, as it does when i switch from run position to accy position since i have to turn the key back.

Just wire it so that the 528t's output triggers the other relay's 85 or 86 coil.  Depending on the polarity connect the other pin to the opposite polarity.  connect pin 30 to your power converter and 87 to 12volts to supply it.

yea use one relay to control the other for example like previous posted

if you set up 528t for a pos output then set the higheramp relay with pin85 comming from 528 and pin 86 ground. pin 30 pos out put to inverter
and pin 87 to constant fused, 87a not used in this app.

if you set up 528 to output a negative than setup relay this way

pin 30 output to inverter
pin 87 constant fused
pin 86 connect with pin 87
pin 86 input from 528t
pin 87a not using in this app.

You lost me on that. I want to set the 528t for positive output.

should i set it up like this:
528t:
red wire 12v constant
black wire ground
yellow to relay 86 pin
BLACK/ white to remote turn on output from radio.

relay to power inverter:
87: 30a fuse 12v constant
30: output to power inverter
85: ground
86: to 528
