I'm prepping to install a fuel injected 2.0 into my car to replace the carbed 1.8. On the 1.8, my fuel pump was located at the firewall near the battery. I didn't label these wires and wondered if anyone could confirm that they are for the (former) fuel pump. They come out of the harness that winds around the firewall. I replaced the engine tray on this side, so they're currently not routed down if they are for the stock fuel pump location. Also, there's a random green with black thin wire with no fitting (ignore the yellow haze from some overspray). Any ideas on this one? I'm moving the fuel pump up front.
Thanks! Bryan Attached image(s)

Bryan I’m pretty sure the green with black goes to your oil pressure sender. Not sure what the rest of that is. |
