astra 1000rs 03 grand caravan

Hi,

I've purchased the Astra 1000rs and would like to install it into my 03 Grand caravan. K9-Classic currently installed.

1) My problem is the van has two starter wires and the RS only has 1 starter wire and 2 ignition wire.  How can I hook this up?

2) Is it possible to use the starter-disable relay as anti-grind also?

3) I know I will have to trip the K9-classic into thinking the ignition wire is not energized during RS.  Can I use pin 11 blue/orange wire from RS (ground when running) to relay to cut off power to from ignition to K9-classic.

This is the link to the RS installation manual and everything is pretty much on page 12+13. http://www.scytek.net/pdf/product_astra_starter_1000RS_manual.pdf

Thanks
