A few thoughts...
1. You might need a bypass module. What color is the plastic head on the ignition key?
2. Dump the quick splice connectors and solder your connections.
3. The two accessory wires are separate circuits for a reason. Keep the separated. Use a relay for ACC2.
4. There are several wires that share the same color pattern in the ignition switch harness. You must test to be sure
you are connecting to the correct wire.
Soldering is fun!
