eXo Posted December 3, 2003 Share Posted December 3, 2003 Hi Guys, I just bought a 2nd hand autometer air/fuel ratio guage. It came out of a GTi-R pulsar and I'll be throwing it into my 1jz '94 Soarer. Has anyone installed these before and if so, where is the air/fuel wire that goes into the ECU ? The closest I've seen is to find the sensor and tap in there. Has anyone installed a similar guage of any brand before. If so, where does the 3rd wire go ? The autometer site is pathetic for tech instructions. <_< :whistles: Quote Link to comment Share on other sites More sharing options...
