1987 5.0 t-bird Orange wire? Where does it attach? Reply #2 – April 03, 2013, 12:03:11 AM Ok, that's weird because my folks are the original owners and I'm sure the intake or the like were ever removed.I wonder how it got taken off? Maybe when they had a climate control issue (automatic controls).The way I noticed it was changing the stock heater hoses back there it surfaced and I figured it must go somewhere.Can I locate it on the motor in a more accessible spot?Why didn't a code show up for this not being grounded?Had a code 63 TPS low volts, replace OE TPS with a BWD from O reillys.Now it idles better without dying, but my mom said when she parked it today it shut off when she went into Park.Maybe the comp is still "adapting"?I disconnected the batt for 10 min. after new TPS install.Thanks for your reply. I really appreciate it.I,m new to the Ford EECIV system. I have a 1989 Jeep 4.0 that I have turned every nut and bolt on lol. Quote Selected

I have mine grounded to one of the bell housing bolts as its just easier to get to and my heads are aluminum so I figured it was a better ground.Darren Quote Selected

Reply #7 – April 03, 2013, 10:19:33 PM Ok, thanks for the help guys.While we're at it, how do you get to the passenger side o2 sensor to remove it?Look at all that stuff routed in such a tight area!Changing that rear intake 3/8ths heater hose was a battle!The OE Motorcraft I took off was a way better hose than I replaced it with:mad: Made in Mexico:toilet: Quote Selected
