So am I am doing a full wire tuck on my EM1 now i was looking at the obd2b ecu pin out and i seen that i have about 80 pins, for things like cruise control and automatic tranz gear indicators... now i am building a mil spec harness from the ground up. I live in ut and still have the pretty tough emissions, so i have the stock b16 that i drop in to pass and another b series that is for that track that i run obd1 on. my question is if i only use the basic sensors and remove all of the auto tranz gear indicators, ac, charcol canister, cruise and others like that will i throw a code if i take those out? Thank you so much in advance!

 

anyone?
