Electrical and Vacuum Troubleshooting Manual.  Very useful and they pop up all over ebay.  Make sure to get the correct one for the specific year of each car.  You'll find yourself referring to it a bunch, even for everyday problems.

I aquired my first EVTM off of ebay.  It's the  one for the 87 cougar that I will be robbing a good portion of parts from.  I got my garage completely cleaned out so I should be getting the bird in there this week to start unhooking everything. 

I was curious about my exhuast.  I have been reading Erics tech section on this over and over.  I don't want to try to fit up a new exhaust system myself so I would take it somewhere.  Would I be able to reuse the cats from my bird and just tell the ler guy to run duals.  Or is there a better choice?  The only reason I ask is because I had new ones put on about 3 years ago and I would hate to buy new ones.  Thanks, Jason.

For exaust forget the stock converters... Get Mustang headers and H pipe, then have a ler shop connect them to the '88 dual lers.

You are going to need to move the fuel filter off the frame rail for clearance on the passenger side, just swap to the fuel lines from the '88.

I am in the process of taking out my engine.  I have fluids draining as I speak.  I have aquired EVTM's for an 87 cougar and my 85 t-bird.  I have gotten a little crossed with the whole speed density and mass air thing.  I understand the diff between them but not how it relates to the phylical wiring.  As I look for engines I can obviously find better used ones from a 92 mustang than I could from say a 85 mustang because of the actual age of the car it came from.  The newer the engine the better, and the fewest miles the better.  I am trying to do this as cheap as possible but not at the cost of it being done right.  Since I am putting this into the 85 bird no matter what I do I am going to be putting in a new wiring harness.  The question is from what or where?  I have an 87 Cougar at my disposal for free so I just figured I could use that harness.  But now I am seeing that its for speed density only.  I don't have to use this car for everything if it's easier to get a harness from something else.  I will modify this motor at some point but prob. not for about 1-2 years.  My questions are;  Can I get a 89-93 stang motor and still use the cougar harness configuration with speed density?  OR would I just do mass air and get an aftermarket harness or stang harness?  Is there any difference in difficulty for me in my application in doing speed density or mass air being that everything is going in new for me anyway?  I need to make sure that I am hunting for the right motor so that when I see one that is a good deal I can c00ch it up. 
Hopefully I will have this motor out this weekend, so my final question is what do I leave in the engine bay?  Should I take out everything engine related?

Thanks for your help, Jason.

If you go with a Stang harness you'll need another EVTM, as there are several differences from the Bird/Coug piece. You can use the Cougar harness, and convert it to mass air with one of the kits the Mustang suppliers sell(they are on ebay as well, Approx $40). BTW I have a '87 5.0 Bird harness in my TC that I converted to M/A.

There are 5 wires that need to be added to the harness for mass air, four for the MAF meter, and one added for the fuel pump monitor(optional, but the MAF EEC will throw a code 89 if it's not connected). Also there are two that move position, and thats it.

So I could potentially put in the 89-93 motor and and set the rest up as speed density from the 87 cougar wiring, coutgar air cleaner assembly, and sd computer from stang and convert to mass air when I want to do some mods.  Thats prob. what I will do unless I buy an aftermarket harness.

I am unhooking everything in the engine compartment (radiator, ac stuff, ps pump, and fuel already disconnected) and I am currently looking at the primary wiring harness and I see 6 wires going to the plug in the drivers side firewall, and everthing else going through a grommet in the firewall on the passenger side.  Where does this unplug at?  I guess I will have track each one down and unplug it.  Please don't tell me I have to take the dash out.  I had to do that twice for the heater core before, no fun to be had there.  I am trying to leave all of the wiring on the motor just to keep it simple if I use this engine elsewhere.  Thanks, Jason.

They connect to the 60 pin plug on the EEC...

Sorry, for some reason I was thinking there were multiple connections.  I was just having a dumb moment, I should have looked before I posted.  I have all of the engine stuff disconnected (except at motor mounts), now I need to go after the exhaust and transmission items. 

Thanks, for your help.

Ok, the damage is done.  I got the engine/transmission out along with all of the wiring.  Now I have to clean it up and paint it with some black heat paint, then start on the wiring.  I have made some decesions.  I am going with a 5 speed rather than auto, and with speed density with all the wiring coming from the 87 cougar I have been given. I will run the mustang H pipe setup for exhaust with no cats.

Should I look for a certain type of T-5?????  I saw on Eric's site all of the different model #s and specs.  Is there enough difference in the oem T-5s to bother worrying about it when I am looking to purchase a used transmission.[/IMG] ??? 

Here are some pics of my progress. (the easy part) If the pics work.

I tried resizing those, I don't know why that didn't work.

Looks like everything is going well so far Jason.  Of course, tearing stuff out is always easier than putting it back in.  ;)

Good to see you on the boards again, btw.

well, youre also going to need the cruise and throttle cables from the 87, seeing as theyre different from your CFI bird

the plugs on the drivers side of the engine compartment, are those the ones in question?
It's Gumby's fault.

Yes, If I am not mistaken, those are what I will need to splice my 87 cougar harness onto.  And just down the line from those is the plugs for the headlight/turn/horn/marker lights.  I haven't retrieved the 87 cougar harness yet.  When I do I am sure I will have bunch more questions.  I am going to try to put the wiring together in a couple of weeks after I have cleaned and painted the engine bay.
