2000 Toyota Sienna Amp Bypass

[Sjohnson20]

Hi, I'm trying to install a new head unit in my Sienna but I want to bypass the factory amp. I see lots of amp bypass wires in the autotoys store for different Toyotas. But theres none listed for the 2000 Sienna. I emailed tech support and they told me to buy the regular Toyota harness from the web site. But when I look at the connectors on the amp it doesn't seem like that harness will work. This is what the amp looks like:
