Tyler.quest3666 Posted October 7, 2015 Report Share Posted October 7, 2015 (edited) Dont want to sound dumb but I'm Installing AFR gauge. what ground do I use? the actual ground that is wrapped around the 02 sensor wire or the ground next to the Ecu? Also what and were is a good switched power I was going to use the radio but I've heard it might screw with the gauge. Secondly my windshield wipers will not stop going unless I unplug the motor. I have cleaned the old grease out and cleaned the connections and it still won't stop Thanks in advance.

scott87star Posted October 7, 2015 Report Share Posted October 7, 2015 Use the ground next to the ECU, the "ground" around the O2 sensor wire is actually a shield, designed to block electrical noise and not to properly ground an electronic device. For switched power you could tap into the ECU power, blue/green connector red wire. For the wipers I would guess your column switch is bad.

Tyler.quest3666 Posted October 7, 2015 Author Report Share Posted October 7, 2015 Thanks for the quick response I really appreciate it. Just want to do it right on the blue connector the two red wires are both switched power correct? And as for the wipers the speed of the wipers work fine but the on off switch is probably bad I'll dig into that and thanks again. Quote Link to comment Share on other sites More sharing options...
scott87star Posted October 7, 2015 Report Share Posted October 7, 2015 Yes, both red wires are the same, switched 12V power from the main relay. Quote Link to comment Share on other sites More sharing options...

Tyler.quest3666 Posted October 9, 2015 Author Report Share Posted October 9, 2015 I'm installing a boost gauge as well can I run the same switched power to both gauges? I Will be using two different grounds and they will have there own in line fuses. Quote Link to comment Share on other sites More sharing options...
