A wiring conundrum

2nd pic...for cruise control I believe

Thanks!!

Even though they share a lot in common, i don't think the 'BuRacing diagrams will help you with the picky sh*t. First thing you need to acquire is a proper service manual for your 85.

If you want to keep the factory sensors, dash and body function, then Nick is correct. The best place to staret is a factory manual. I have them, it will eliminate all of the guessing.

I went on line looking for any of them but, I can't find any in Canada, as of yet, and getting them from the US, the shipping costs are more than the price of the books and, converting from US to CDN dollars is a killer! $.75 US will buy $1.00 CDN

I paid $100 for our Cutlass manual - it's alot, but well worth it a couple of times.

So, what's your question?

I had a similar 5 wire plug in my 83 Malibu wagon. Wire colors look to be close. The green wire from mine went to the AC. It was for the high idle solenoid. Had to save that one. I think you'll need to open up the split loom and trace these wires from where they start/end.

Oh God! I absolutely hate wiring! LOL That may be my only option though I guess!

Just wondering what the wires that are hanging should be hooked to? With the intake and the rest of the set up that was in the car there weren't any sensors to attach any of them to! The first picture has 4 wires Black, light green, dark green and brown! They go into the main wiring harness right beside the distributor! The second picture is a dark green wire that comes out of the main wiring harness right below the brake booster!

85 probably had a computer, which sounds like is not operational. All the computer wires are in a harness that ducks under the heater box on the passenger side. The main engine, heater, and lighting are in the bulkhead connector on the driver's side. Cruise control wires come out lower and under the brake booster. The maliburacing diagrams should pretty well cover the bulhead connector wires, not so much on the cruise and computer.

Wires are all attached to the computer, black, Blue, Grey, Beige and orange!

Even though they share a lot in common, i don't think the 'BuRacing diagrams will help you with the picky sh*t. First thing you need to acquire is a proper service manual for your 85. Place called Faxon, accessible on line, offers manuals for sale. Next thing you need is a windshield wiper motor and be aware that they come in more than one version and vary from the standard 2-spd and park through intermittent to low to high speed. Once you identify the harness for that unit, it will tell you visibly what version you had. The switch, either on the dash or on the turn signal stick, can also offer clues.

If your new project did have that first Gen EEE or ECU or whatever the flavor of factory title it got graced with, it would have been located behind the passengers side kick panel just under the dash at the bottom of the A Pillar. Chances are good what you will find is either nothing or an aluminum box that has no wires running to it or they are just hanging in the wind. There have been discussions about these dinosaurs uploaded to other rooms on this site , so only thing to note is that the power for it came from the 3/8ths stud on the starter solenoid; you may be inch-worming around under the motor and find the wires just hanging, or they have been mutilated by clipping off the ring terminals and left to rot.

There is such a animal as a 350 CID Olds if memory serves. Totally different physical appearance than a Chev. Not about to get into the what should be in what scrimmage; that is an ongoing and endless debate.

It would be useful to have a full shot of the engine showing topside and then profiles of each side in turn, just to see what did get connected and what is just flopping around by way of wires. In picture number 2, that connection is a five wire weatherpak connector, the female half. It should either mate to a matching five pin female or be a plug in to a socket. YOu did mention A/C but not on which side it used to be located. I will leave this to the Olds specialists on board but think it possible that the A/C compressor may have been located differently from side to side depending on if the motor was Chev or Olds/corporate. If the compressor is mia then it may have been the destination for the large *ss five pin connector currently hanging around.

You should be aware that, without the "computer" both the distributor and carburetor are very limited in what they can do and accomplish. Both these items sent data to that box and got feedback from it. The essential difference is/was that it did not do any data logging and could only respond to input on a fixed and limited basis. It can be tuned or tweaked but that is again, a topic located elsewhere. if the box is, in fact, disabled or gone, you will likely have to determine what versions of your carb and distributor you have and whether they can stand alone without the assistance of an E-brain in the equation.

All the wires are connected to the computer, black, blue, grey, beige and orange and is connected to the starter solenoid! The first picture is of the wires in question, they come out of the main wiring harness beside the distributor, light green, dark green, black and brown! The second picture is a dark green wire that comes out of the main wiring harness below the brake booster! One of the 2 dark green wires should go to the temp sensor but, which one is the problem! Aren't I just a real pain in the butt!
