Sup all..... heres my question.... I have a 02 sensor from 90 integra that has only 1 wire in it.... I already welded a bung to my down pipe to put the o2 sensor in.... I was wondering if I can use this with my autometer air/fuel gauge so it will be directly connected to the 1 wire of the 02 sensor instead of tapping it in the ecu???? Please need help this is for my friend that has a 89 hb civic w/ b16a turbo. Thanks in advance!!!
