AC line diagram needed. 84 T-bird 5.0L (I searched for it but I need help still)

I have an 84 with whatever (I think it's the evaporator? that is in the HVAC box) That plus a compressor (84 or could be 86) on the 5.0L.  I need everything else pretty much but not sure about what all is in the system.  I tried google and several other places but couldn't find the whole picture.  Basically the 2 lines, 1 bottle (Accumulator) and I think some type of coil by the front bumper.  But i am not sure which that is.  If anyone could help me out to make sure I pick the lines from the correct year car I would be very grateful.  Here are some pics to help.

Edit:  I think I am going to buy most of this stuff used.  Here is an o-ring kit that looks like the right system. http://www.ebay.com/itm/A-C-System-O-Ring-and-Gasket-Kit-Rapid-Seal-Oring-Kit-UAC-RS-2520-/181141708615?pt=Motors_Car_Truck_Parts_Accessories&fits=Year%3A1984%7CModel%3AThunderbird&hash=item2a2ce31f47&vxp=mtr







She's a dirty motor but that's because replacing the 30 year old body parts/suspension has taken up some time.  It's not leaking oil but needs EGR etc hooked back up.  I have to do the AC first.  Heat works good.  This is about 4 years since I put the motor in the car.

Yup still have a few unanswered questions about the AC system.  Mainly the diagram for the electrical would be about it.  I went to pick n pull and grabbed an accumulator (They called it a dryer) and a condenser. (I think that is what it is) and picked up brand new o-rings for it.  I need to pressure test the condenser to make sure it's not busted from being in the junk yard.  I pulled this stuff from a 3.8L 4 eye mustang but it looked like the same system the car used  to have so i figured it would work. 

Here are some pics of the parts.







I don't know what wires hook up to the compressor and accumlator.  I will figure that out later since I forgot to grab the wire that was on the compressor at the junkyard.  I will have to go pay the dollar to get in and snag that.  Hopefully A/C time soon.

If the compressor has been exposed to the elements for a while, I'd recommend taking it off and pouring some oil (ester or PAG) in it. Rotate the input shaft a few times and drain it before adding some more oil.

Also, flush the evaporator because it's got a decent amount of mineral oil in it that won't be in the best shape after being exposed for so long (also, mineral oil isn't miscible [think oil and water] with R-134a).

I'd toss the accumulator/drier and get a new one. It has a desiccant bag in it that pulls the moisture out of the system so it doesn't turn into an acid. If it's an original accumulator, the desiccant is probably saturated. It's the only part of the system that 'goes bad'.

I'd also flush the condenser to get the residual mineral oil out. Residual mineral oil takes up space and decreases system performance a little bit.

You are a savior don't let anyone tell you differently.  I've been out there for hours wiring this thing up.  I have just about everyone in the diagram already located and laying there.  This diagram is so much better than the one in the haynes manual.  I think I will be running again tomorrow, hopefully the system itself doesn't leak and the compressor works.  Thanks again softtouch this will allow me to compete the work.  .

NOT PAG it is not compatible with paraffin oils. Never use PAG on a conversion when you are using 134A. have a great evening guys
