Drawtite Part #36196 $104.95
I will confirm that it is the Drawtite 36196. How were you able to get that number off the Drawtite site? When selecting vehicle I did not see Saab listed. The trailer lighting control unit I used was the Drawtite Modulite Lite part number 18187, listed on their site at $23.25. So if the hitch is $104.95 and $23.25, then in total you are paying $128.20, not to bad for everything you need for the job. I have written up some instructions for for doing the wiring part, but the instructions that came with the control unit were quite good and guided me through the set up. Hardest part was figuring out which Saab wires to tap into for the unit. Thread on this subject is here: http://www.saabcentral.com/forums/showthread.php?t=49675
Unfortunately its raining here today, so I doubt I'll be able to get any pictures of the hitch installation, but like I said, hardest part is getting some of the bolts into position, which can be fixed by using a length of wire to get them in place.
OK, in the middle of this post I got bored and made some crude drawings:
This crude drawing is how you want the bolts to be positions. Mind you I believe that are a few washers involved that aren't 'pictured. Their are two beams that run from the front of the car to the back, one on each side. The view in the drawing is from the side. The These are where the hitch attaches. The beams are enclosed except for where the 'access area,' which is seen if you were looking towards the outside if your head was underneath the spare wheel well. The bolt that is towards the front end of the car (closest to access area) can be put in by hand. The problem is the one to the rear, the only access you have to put that bolt in is the 'access area'. So, as I had learned on this site, you run a piece of bendable wire through the hole for the bolt (the far one), and manipulate it so it runs up the beam to the 'access area'. Once you have it through there you wrap the end of the wire at the 'access area' around the bolt that you are putting back there (first put all washers, etc. that the directions describe for the inside of the beam on first). Make sure you wrap the wire as tightly as possible around the bolt, you have to get the bolt and wrapped wire through a very tight space when you get it into its final position. So now you have something that looks like this (the red is representing the wire):
Now you just need to carefully pull the wire from the end where the bolt will be in its resting place. Something like this:
So there you have it. One thing I realized while writing this is that my 'access area' may be in the wrong place. It may be towards the back instead of the front, but the theory behind getting that far away bolt into place is the same, just going in opposite directions. Its the same situation for the other beam, just use a piece of wire to pull it through.
Oh, and as for removing the rear muffler to gain space to get the other side of the hitch into position as the Drawtite directions state, not totally necessary. I think I may have released the rear rubber hanger, but that was it. Just need to pull the muffler downward enough to get that side of the hitch into position.
EDIT: One thing I forgot to note: I noticed later on that the rear-most driver's side (US) bolt sits awefully close to the rear muffler. I'm not sure if the muffler and that bolt ever make contact, but I did wrap some electrical tape around the bolt to soften any blows that the muffler may take from the bolt. Might be worth doing the same.
