Build Thread Mustang5L5's Build Thread -

Let me clean it up a bit and then pass judgement. The Motorcraft sticker is gone now (it was falling off) and a quick wet sand does make it look a bit newer. Let me work on it and give it another shot

Built a Mr Fusion smoke machine.

Puts out tons of smoke, draws 5amps when running and smells like a citronella candle. No idea if it will go up in flames but keep an extinguisher handy.

Waiting on some tubing and then I can do a quick smoke test just to cross off that box

Starting to get into the finishing touches now.

New grill. Amazingly these are still available. Tasca Ford has them for $55. I did pick up new hardware from LMR, as my screws were all rusty.






Unfortunately my plan stalled out trying to get these originals out. They don’t come out easy. Not sure how hard I’ll try as they still work, but I just want to ditch the 34 year old rusty ones.


Decided to check out my original grill , to new Ford production. I checked out the markings on the backside and they were spot on. 30 years separation.

Original on top. Check out the scratches on the part number.

Nice! That’s the one from Brew2l?

Yup. Simple enough to make.

Decided I wanted to try and eliminate some useless codes. Made some resistor plugs for the TAD and TAB

Lopped off the ends of a junk pair of TAB/TAD I’ve had in a box of spare parts.




Next up, exposed the terminal ends and then drilled a small hole in each


Added a 75ohm resistor and soldered it in.



A little heat shrink and done.


Plugged them in and zip-tied out of way. I realize this is quite useless, but I had the parts so why not? This will eliminate the code 81/82 during KOEO code reading.

You will still get toe code 41/91 during KOER testing though. Nothing you can do about that other than put the air pump back on.

Still working through the EGR not working. I know it’s getting removed eventually but I still need things to work.

Saw that those EGR resistor plugs are now $100, so I figure I’d try to build one or two myself. I’d rather get the EGR functional for now, but I wanted to see how it involved it would be to build 2 or 3 of these.

So found the plug kit online
Aokus Compatible with Ford Mustang egr EGR harness connector plug - 1986-1995/86-95 5.0L V8 and 2.3L four cylinder Amazon product ASIN B091Z453GTView: https://www.amazon.com/dp/B091Z453GT/ref=cm_sw_r_cp_api_glt_fabc_RWPQBC094QMCEXRFATZD



Unfortunately whoever is putting these kits together is supplying the wrong pins. They send them out with female pin. Unfortunately you need male pins.


So I found these
25 Wedge Lock Terminals 20-18 Gauge .110 Male Pin Dia. Amazon product ASIN B0040D0R7EView: https://www.amazon.com/dp/B0040D0R7E/ref=cm_sw_r_cp_api_glt_fabc_MTHHDGWCWQ4VSZ09EF0P?_encoding=UTF8&psc=1





This pin will work. Now to wire it up like the diagram shows



Quick project one night, and test it out. My understanding is the resistors simulate a fixed closed position which prevents the CEL from lighting, but also turns off the EGR function in the ECU.

As far as the EGR not working,what was used in the way of intake gaskets?
Are the gaskets blocking off the EGR passages?

I want to say I wouldn’t have goofed up and put intake gaskets that lacked the EGR port, but it’s possible. I’m trying to look back at my thread or find a receipt but S/N for some reason is not loading my older posts.

The reason I think you might be right is because I manually opened the EGR valve at idle and nothing changed. It seems like there is no flow at all. The heads do have the ports, but maybe I did slap gaskets that blocked them off

In that case, EGR resistor plug and block off plate and call it a day.

Can anyone go back and view page 1 of this thread? It times out when I try to go back
