    wiring help

    i have a 2001 LS1 throttle body, which i am installing on a 99 3800 s/c motor. I need the wiring for the TPS sensor?, it`s a three pin connector. also i have a mass air flow sensor from a 2001 chevy 8.1 liter truck, which i am using with thw LS1 TB. the MAF connector has five pin connector (two for the IAT sensor). does anyone have the wiring for the pin connector?. what i am looking for, is the labeling of each pin on the TPS and the MAF sensor.

    my 93 info has same pinout.. but diff colors. So just a matter of matching that to your harness colors since it looks like thats a GM standard configuration...
