For the Fuel Temp sensor, the Red/Yellow wire Pin 18 from the Impreza B99 goes to Red/Lavender(blue) pin 27 on the H6 connector B99. Hopefully the sensors are the same. That is something I don't know. The other Temp Sensor wire Black/red Pin 7 Impreza B97 will go to Black/yellow Pin 13 on the H6 B99. Make sure Pin 13 goes to 12v with the IGN key ON. That will also supply power for the fuel gauge. On B97 you are right about L/y hooked to Pin 6 R/b for the fuel pump. The W/B colored wires go together for stop lights. And Pin 5 is ground.

Thanks, I wanted to be sure. Right now I'm also working on a laptop for a friend, but I'll get back to you soon.

At least he has a sample to take to a cable maker if they exist any more

The pin layout on the fuel pump connectors R58 are different between the two vehicles. The fuel pump gets power from pins 1 and 4 on the 97 and pins 1 and 2 on the 03. And the Fuel Temp sensor pins are different. Besides that, the later model uses a Fuel Pump Control Module which the 97 does not have. Both use a fuel pump relay, but on the newer one the Fuel Pump Control Module supplies a hot from the relay and also a ground to the Fuel Pump. It will take some time, but I will try to sort it out and see what wires must be moved on the B99 and B97 connectors.
