So i bought an old van and it came with a Avital Champion Mark 3 alarm. I dont have the remote.

I want to install a new Viper 3501v alarm. I figured all the wires are already tapped, so i just need to connect the right wires from the new brain, to the the old wires. Can someone tell me exactly which color wires i need to attached from the Viper 3501v to the existing alarm? Here's the pictures of the alarm. From the research that've i've done, some say it's the same brain as the Clifford Ace 500 or the Clifford XL1000 with the same pin layout but different wiring colors.

Thanks for any help!

Here's what i Have
