stilo to pioneer DEH-4500BT

[joshstilo]

Hi,
just to start...i'm terrible with wiring so please be simple

i have a pioneer DEH-4500BT that i want to put in my stilo. it was previously in an Astra. The loom does not have the red and yellow bullet connectors mentioned in the sticky post about sony. Any suggestions or links to the correct loom to buy or what to do would be great.
Thanks very much in advance, Josh
