Boosted89sc - I have checked my manual and yes that is the sensor ( Pressure warning switch ) - 5 Pin connector. I do know that it was the green one... believe it was about 2 1/2" long or so & cylinder shaped as well and the bottom of it is where you would use a wrench to loosen it. 7/8" maybe, really can't remember.
Yes... You will have to pump the brakes 20 to 30 times with key off to discharge the pressure in the system before disassembling.
Getting to it is easy but requires you to take off your wipers, cowl panels and the wiper motor. take those off and it well make life soooo much easier.
Once you do all that discharge brake system like I mentioned above, then take your Accumulator off, making sure you do not lose or damage the O-Ring.
next you will need to dis-connect that little brake line ( the 5" to 6 " wavy one ). then dis-connect the hose from the reservoir to the pump. leave the one end on the reservoir and just plug the other end with something.
then your next step is to take the pump off. there is a plug on the shock tower side (pump motor connector) you will need to unplug. the other side... there is a small headed bolt with like a rubber type gomment/ fitting which ensures pump to move freely when pump comes on. take this bolt off and you should at this point take the pump out through the hole created when you took the Accumulator off. Watch as you are pulling out the pump to help feed the pump motor wire through and around all the other wiring / hoses/ brake lines. Will hang up and piss you off if you aren't watching what you are doing. lol!
now that you have the pump out, you now can get to the pressure waring switch connector. As I mentioned in my previous posting there, on replacing the O-ring. Before Re-installing the switch... lubricate the O-ring with a little bit of brake fluid. now you are ready to install everything back. GOOD LUCK!
I really hope I haven't confused you or left anything out here and I hope you can follow what I wrote as well. I hope this Helps!! If you need any help just AIM me at : brattmanjc89. or email me at

P. S. - I surprising did not have to bleed my brakes neither I thought I was going to have to when I put everything back together and started my car and watched to make sure both the ABS light and the brakelight to go off after about 10 seconds, I then pumped my brakes and they were hard. I then drove it out of the garage to test drive it, making several quick stops.... all was COOL! I then was Very happy!! But this does not mean that you might have too though. It wouldn't hurt to do so anyways, just to make sure.
