lt1 shift light install
i have done search's and have still had no luck in getting my shift light to work. it is a proform and i have power but i dont know which wire to splice into to get the signal for the rpm's. i found on here that some said the the 13 pin in the red connector for the pcm but i tried that and still no luck. could someone that has hooked one up before please tell me what color connector it is in and what color the wire is. i got it to work by splicing into a wire going to the ignition module but that caused a missfire so i took it off. please some one help me!

OBD 1: White wire, red connector on PCM, pin #13
OBD 2 LT1: Same as OBDI PCM
98 LS1: Tach line is Pin 35 on the BLUE connector. Tach line is a white wire
99-00 LS1: Tach line is Pin 10 on the RED connector. Tach line is a white wire
it's worked for me....check all your connections
