Orange wire September 02, 2007, 10:30:00 AM Unhooked comes from the white connector thats attached to the intake.Any body know where it goes.the only orange wire on the schematic that I got says oxy ground but there hooked up. Quote Selected
Orange wire Reply #1 – September 02, 2007, 12:17:52 PM please double check for a secondary color.your o2 sensor does get an orange but that orange wire parallels off to actual chassis ground. i suppose the branch will connect to the rear of each head. Quote Selected

Orange wire Reply #4 – September 02, 2007, 02:49:47 PM its possible its a chassie ground for your harness. look on the firewall near the tb for a connector. Quote Selected
Orange wire Reply #5 – September 02, 2007, 03:23:45 PM I looked at an 88 tbird can't tell where it goes unless I start cut her harness open,You know I think I need a carb.less shiznit in the way.This sucks when the valves aren't ajusted the first time right.Gota go put the cobra top back on.If anybody knows let me know.

Orange wire Reply #8 – September 03, 2007, 06:45:38 AM Yeh Jim next to the big black one mounted to the intake.I'm going to run some codes today.It's running real good. Quote Selected
Orange wire Reply #9 – September 03, 2007, 09:06:28 AM I'm not sure if the wire coloring is the same between Mustangs and Tbirds, but here's what I have. If it is an orange wire, it is a o2 ground. If it's a orange/white, it is the feed for MAP, TPS and EGR.Jim Quote Selected
Orange wire Reply #10 – September 03, 2007, 10:38:48 AM I have o2 grounds coming out of the o2 harness to the heads.I even unraveled the harness and theres no other orange wire to hook to.It could be a ground I never hooked up when I put the motor in,and happen to see it now.I'm going out soon and play with a few things.

Orange wire Reply #11 – September 03, 2007, 10:42:05 AM I have the same thing. We've discussed it before.It's like that on my '88 and was like that on an '87 Bird I grabbed the harness from in the yard.http://www.foxtbirdcougarforums.com/showthread.php?t=13201&highlight=orange+wire+harnesshttp://www.foxtbirdcougarforums.com/showthread.php?t=14430&highlight=orange+wire+harness Quote Selected

Orange wire Reply #13 – November 10, 2008, 11:47:23 AM Hmmm....Should this show a code?I would think not if I have the right idea in my head.....See the pic below. If that's correct, it will have no real effect on A/F ratio or open/closed loop...You might short something out though....Do I have this right?Wiring was never a strong point with me.....trying to learn more and more.
