my friend just wrecked his evo and was parting it out so i bought the seats and the wide band for 500. thing is i don't have instructions to install this in my car i have an 88 hf with an zc swap, si ecu. i have an aftermarket header with an extra bung for another o2 sensor. what are my options to install the wide band do i replace the stock narrow band or do i install it more downstream in the extra bung and keep my narrow band for the ecu input. how do i wire this up to my stock ecu?

sorry i'm noob when it comes to wiring and electrical thanks for the help in advance.

 

anyone have maybe a link? i went to the innovate site but they don't have any instructions for pre 92 hondas.

 

bump want to install today
