I don't how I could possibly ignore this information...

Anyway, No I have not yet tapped into pin 34 as my evtm made no mention of anything coming from pin 34, but the DOL could very well be coming from my A9L cornputer which Jeremy's link kind of sort of eludes to.

Now unfortunately I'm short pins to pin a wire into the main harness, so I am currently unable to test this theory. But, perhaps there is someone on this forum with either a digital dash or a tripminder that has converted to mass air and is able to confirm whether or not a mustang processor generates this signal.

In the mean time I guess I'll try and locate a harness pin (I junked all my old wiring:nono: ) so stay tuned? And thank you Jeremy for the Fuel Injection Strategy document that is much better than the baby.

Pin 34.

Me neither. :hick:

Try and know who you're talking to before you assume they're giving bogus, useless information.

Ok I have been looking into this and from what I can tell fuel flow info comes from Pin 34 DOL ( Data Output Link). The A9 series does not offer this output in their strategies. So no it's not possible to show fuel mileage on the mustang ECU.

The EEC strategy document I linked to is for the A9L. A9L=GUFB.

The DOL is available on the A9* series.

Mine works with the A9.I don't believe it though.
I use gauges!.

i just installed a tripminder in my car as per the instructions in this thread and it went in just fine just have to run the wire to the ecu pin so i can get a realistic reading(i know im not getting 94mpg lol)
it was not fun drilling out those rivets by hand, and drilling into my hand when the popped out :hick:
i used hot glue(from my unused ding king kit) to glue the brackets onto the tripminder housing and it held the brakets on just fine.
i got mine out of an 89 ltd wagon and managed to pull the whole harness to it out with it which made it stupid easy to do.
on the harness i got theres another squareish plug attaced to it that the fuel flow and speed input run into along with the blue w/red stripe and a black wire, the other plug is just like the original units plug.

ok, since it was nice out today i fugured i would tackle this.
i ran my wire to the pin #34 on the ecm and connected it to the fuel flow wire at the tripminder and im still getting a high mpg reading.
on mine the wire pin-out has a light blue/pink wire for the fuel flow output at the tripminder end of the harness, which runs down to the plug in harness behind the dash. on that end the wire is still the same color in the corresponding point on that plug behind the dash.
i guess it doesnt completely run all the way to the ecm somewhere down the line.
on pin #34 on my ecm the wire happens to be the same color(ltblue/pink) which i tapped into. even after i ran the wire straight from the ecm to the tripminder pin for fuel flow i dont get a reading for the gallons used part(always reads .0),the instant Kilometer per gallon and still get a high mpg reading.

heres some pics.

wOOt!
I feel special.

This is how I celebrated CJ08!

It was truely plug and play, a TM from an 84 TBird Elan, into a 1988 Cougar Xr7. The only thing I got confused with was Pin 34. The book referred to it as a DOL (data output link). Pin 34, Circuit 305 Light/Blue Pink worked like a charm, but I was looking for something that actually said 'fuel-flow'. lol, so after second and third guessing myself, I tapped into it, and :)

here is a little map of the ecu pins to help find pin 34. I got my trip minder completely working last night. thanks to the previous posts the light blue pink stripe wire worked for me

My tripminder was a lifesaver on the trip out to CJ. As soon as my fuel gauge passed 1/2 it jumped down to below 1/4 and stayed there for the remainder of the drive, but I was able to use the "gallons used" reading from the tripminder to accurately know how much fuel I had. I was *so* glad to have it...

It is a nifty little gadget with many practical applications.
Glad it worked out for you Quietleaf!

'85 TC to 89 5.0 conversion

Reply #86 – March 18, 2009, 03:50:20 PM

I know this is an old post, but I am having the same issue. It sounds like the '89 'Stang harness I used for the conversion does not have an output for the DOL on pin 34. Do I need to pull that signal out and hardwire to the TripMinder? I'm getting crazy mileage numbers, and showing "0" fuel used...There appears to be a brown wire from pin 34 (need to double check that) and the voltage moves between .455 and .560 as I rev the engine. I hardwired this "output" from pin 34 to pin 6 of the tripminder. This, however does not reflect in showing any "fuel used" on the tripminder display...Any thoughts?

If you used the Mustang harness it might not have the pin in the EEC-IV connector. If this is the case you'll have to insert a pin into position 34. The EEC-IV computer itself should have the output on pin 34, but since it's not used in Mustangs the Mustang harness won't have the wire.

Thank you very much for showing me how to properly use that butt splice you have there. I had no idea thats what you were suppose to do with the open end. Just stuff a blade type connector up inside there. Matter of fact, i had no idea that open end had a function.

I sure could have used this on a power plant project where i had to hot tap into a 20awg wire sense lead. I ended up getting everything properly done and not dropping the entire 2000A plant but seeing your connector there, I wish i had known then what i know now.

IIRC, you are pushing the limit on that butt splice AWG limit. I think that butt splice is only rated for 20-24awg,, I know its good for very small wire but that wire there looks to be in the range of 18 or larger.

I installed another Tripminder last night, this time into my 87 TC. I used the clocks short harness and soldered on the tripminder's plug. I took a look at the vehicle harness where the clock harness plugs in and found that the wiring was already there! I then ran the speed and fuel wires with the correct ending pins into the two corresponding unused spots on the connector and it was done. Took it on a quick drive and every works correctly. So some vehicles DO have the wiring already in place.
