I have a 2002 model vy executive i got a new head unit for chrissy how do i go about installing it...
start by asking in the right forum.
You asked in the very first forum for sponsor ASR who modify the original head unit.
Additionally, check out the search function as your question has been asked and answered many a time. To help you out there, here are 2 that seem pretty good.

Installing a new HU in a VY-VZ - How I did it.
As a side note, if you read through those and are still pretty lost as to what to do, I would just 'suck it up' and paid to have it professionally installed.
Have fun and good luck!
