There is only one on a Reatta. If you are seeing two listed it is because one has the factory adapter and the other is a universal with no connector installed.
Nothing from the BCM. I had replaced: all coils, ICM, CPS, IAC, plug wires, TPS, and spark plugs. All had no effect on the issue, and refused to believe that my new O2 could be bad. So I spent alot of time checking everthing else.
I had one that seemed to be sending the correct signal and the computer never through a cold. Heck even watching it while in diagnostic mode it was showing the correct readings. So they can go bad and not throw a code, granted it is nott too common from what I have seen. I had tried everything else and the 02 was around a month old.
The othe two wires are the actual signal they go to the left and rith + input. Use a 1/4 inch female stereo plug, for ease of install. Then all you need is a 1/4" to 1/8" adapter and a double ended male 1/8 cord. The Volume on the Ipod is best kept around 3/4 while using it in this setup.
PSSST!. !!!!!!!!!! Just a note for all. Most ACdelco radio from mid 80s to 95' used the same pin and protical setup. this means almost all have a aux input option and weather it is the brain unit or full deck the aux are ussaly the same. Also yes the common/groung for the aux are the same for the left and right.
It went down just a bit. I account for this from: 1) it is superchared (requires more fuel just to idle and run) 2) If using the tranny that came with the engine, the gearing is a bit lower. I get 20-25 depending on my driving habbits, but I have not been on a full freway tank yet. I would bet a full tank on the freeway would get 27. Keep in mind that it will depend on your tune.
replace your 02 sensor. It does not always sen a signal as being bad. I recently had a simular issue and went through many other checks and replacements, before replaceing the 02. (I honestly believe a high consontrate of seafoam in the fuel caused my issue. (one can in like 3 gallons, just wanted to really clean the fuel system)
I am not completely sure but I ran into a listing for two O2 sensors. The diffrence was one had a OEM conector and the other did not. As far as any real change in the 02 sensor would really be in the ECM limitaion to sense the voltage produced. (not to say a quality 02 sensor would not be more sensitive)
The yellow or red wire provides power for the tape deck. just add a switch to the wire this will allow you to cut the power to the deck, and still be able to power it if you loose battery power. The radio will switch without the tape deck being hooked up, but it must be installed at least once after loss of battery power.
I put my money on the rack being a bit loose. I mean the bolts, I just had this issue, mine was brought on by the square bolt (tack welded) breaking loose from the subframe. You can tighten the rack bolts with 3 feet of extention and a 15mm socket. With out this set up it is very hard to properly tighten the four bolts on the rack. I would also chek to see if the lower blots are still tacked in place.
