successful EATC-to-manual conversion

Today I finished up my conversion, wasn't that hard, even for me. :hick:

Everything works, vacuum and electrical.

I removed some of the excess vacuum tubing, ran a single hose from the TEE over to the pass. side, and connected that to thr vac. canister/ball what's it-who's it, and then tee'd in the hose for the heater assy.

here's the line as it runs to the TEE:


Here's the connector where everything gets to business.
The bottom line runs to the canister on the inside of the fender.


The electrical was a little more involved, but luckily I had a donor car. I pulled ALL the dash wiring from the white car, then clipped out the relevant wiring and connectors. I looked at the EVTM, and the 2 sets of wiring, and simply repinned the Sport's stock heater wires as need into the plugs used with the manual controller. Easy as pie. :bowdown:

In these 2 pics, the wires that are on my fingers are the ones that I repinned into the manual heater's connectors. An EVTM is very nice for double checking things here, as we all know Ford is very consistent with wiring! ;)



 
I know this is rather vague, but if you have the connectors and a few inches of wiring from each one, all the manual parts, and EVTM, anyone with at least 15 brain cells can accomplish this. Hell, I did, and that's sayin' somethin! :rollin:

Hope this is somewhat helpful to anyone looking to this. :D

I guess my only question is what do the swap?  Not trying to be rude, just was curious for your motivation.  Also, I assume going the other way (from manual HVAC to electronic) is entirely not as easy?  Did you just leave all the special sensors in the ducting?  Unless you're telling me you swapped out the entire big ol black housing, I was under the assumption that the electronic HVAC and the manual HVAC had two completely different housings for the heater/AC ductwork, making it a swap that required pulling the dash to upgrade from base to electronic.  Thoughts?

You are correct in that the whole housing has to be swapped. I dare say it'd be a righteous PITA to convert manual-to-EATC...all the sensors, wiring, etc. Hell with that lol.

I did it because I have no need for AC, for simplicity's sake, and because at the time that I pulled the original EATC housing, I was rather sure I had an operable manual housing...which turned out to be a resounding hell no 10 minutes after I'd cracked the original pulling it out. Ouch.

I suppose if one had a complete, unmolested car with ALL the  EATC parts intact, and about 3 tons more patience than myself, then yes, it could be accomplished.

I pretty much wanted the manual setup...hell, when I got the car, the heater hoses had been spliced together...if it had worked, I probably would've kept it...till it did quit. :hick:

This is something I will consider when I no longer have only one car. I hate the EATC system, even when it does work. It takes 10 minutes to turn on the heater.

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.

I had two non negotiable requirements when I bought my TC for the 5.0 swap, no EATC & no hole in the roof, didn't want leather either but that would have been easily swappable... As it turned out I found the perfect candidate, white with black cloth(my preferred combo)even had a auto tranny so didn't have to mess with ditching the clutch pedal...

It's an '88... ;)























It's nothing you haven't seen before...just kicking around a plan.
It's on the backburner, but definitely gonna happen.

Hint: I almost got stung... ;)

Windsor, C4, 8.8  I've decided on that. Should be a good street, occasional strip car. Something to learn to drag race in. Yeah, I said it.

Dunno when I'll get started...have a 351w that's complete, save for a cam, carb, and headers. Need some CHE's, SFC, and another set of Chuck's mounts. Figure out something for fuel lines and an interior....and some GT/TC brakes...good to go. :D

I'll have to check the specs of the cam and see if they'll work with the heads I have for it. Buddy had it in an '82 Stang..was pretty wild. Not sure what cam he had in it, but I have everything else, minus cam, and carb.

We'll see;)
