99 ls1 Firebird help with downstream 02 connector help
so I ended with s friends 99 Firebird 6 speed that was a track car had long tubes and no downstream 02s stock engine harness as far as I know - putting it back on street got all parts he removed and its together and running but I can't find anywhere the downstream 02s plug into on either side? I know they have to be part of engine harness few months back I had 1 plug at back of intake I couldn't find and this picture helped me out - don't remember where I found it because id like to see what all the #s go to - looks like #5 & #8 are 02 plugs but where are the 2 others? I feel kinda stupid as this should be an easy thing
can anyone help an old man out?
thanks Merv! do you know what's plug#2 is for? IIRC #8 is by Alt plug and grounds up by left motor mount? 40,41,42 are for AC comp and EGR or crank sensor? I guess 3,4,5,6 are for T56
2 - Reverse Light Switch on the T56
40 - Oil Level Sensor
41 - Starter
42 - Crank Sensor
3 - T56 VSS
4 - T56 Reverse Lockout
6 - T56 Skip Shift. Can delete that one. Cut it off in a little bit, cap the Pink one and tape it back up.
