Black wire with white stripe, but double check the FSM in case the wire colors varied from year to year.

is that one the signal wire?

There are two signal wires to the circuit opening relay, so your switch needs to intercept the power instead. The B wire (black with a white stripe) is the power supply and the Fp wire (blue with a red stripe) goes to the fuel pump. The switch can go into either of these wires, it doesn’t matter which. Simply cut the wire, extend each cut end to your chosen switch location using the same or thicker gauge wire and terminate them onto the switch. Note that the STA wire is also black with a white stripe, but it’s thinner. Make sure you get the right wire.
