Thank you! I got the gauges all wired up, and tested the power for the blinkers, dimmer, illumination, and bright switch. They all seemed to work, but I am a little stumped on the fuel gauge wiring. From research Ive done, It seems the fuel level comes from the OBDII wire from the PCM, not directly from the fuel level sender, but I already pulled the pin for the fuel sender into the PCM, so I need to figure out what I need to re-pin to get it to work, if it will even work. Also, I see in my notes that the PCM has an input from the tank fuel sender, and a ground that I assume in with the harness grounds. I removed both of these from the directions on LT1swap.com, so I need to figure out if I can put them back in and get the fuel gauge to work.
