I thought the fuel pump positive wire was black with a blue stripe. I know that if you cut that wire the car won't start. wink.gif

Edit: Toyota electrical diagrams say that there's a blue wire with a black stripe that's positive, and a white wire with a black stripe that's ground.

the fuel pump should come with a harness. The harness on the stock pump wont fit into the plug on the new pump. So you cut the plug off the old assembly, and attach the new harness.
