Re: Lq9 swap wiring help needed

Fuel Pump wire, I use 12 gauge, But 14 gauge will work fine.

Purple TCC brake switch wire, You will need a Dual Pole Brake Switch, '85 Chevy C10 w/ cruise is a good application, How to wire it has been covered several times here.

Cranking signal wire....Not needed.

AAW VSS power....Not Needed. Your PCM has a 4000 PPM signal out of the PCM for an electric Speedometer.
