straight up. everyone screams tune it tune it blah blah blah but what the hell am i to do if i dont have an aldl port? please dont sya go install one. nor ask why i donth ave one : it didnt have it when i got the car, its still not there....


the dealership installed an alarm. and a valet switch. could that have any thing to do with it?

 

You didn't post what ECM, year or type of motor so it makes it difficult to give specifics.
There IS a pin from the ECM that carries the data. You must run a wire from that along with a power and a ground to a communication "cable" that you can make or buy.
It's just a matter of figuring out which pin it is and making the connections as needed.
You don't have to install the whole port. Just the wires to make the data line work.

Well.....

One could find the correct wiring diagrams for your car that refer to the ECM and find the ALDL data line out. Typically 730/165 ECMs are Pin A8 or A9.

I don't see why a installer that had half a clue would move or hide the ALDL port.

Would that call for a point reduction in a IASCA competition? It should! Most annoying thing for me as a tech is to have to remove a trailer brake controller, etc to pull codes/datastream info on a truck. /soapbox

What year, engine, etc is your car?

 

92 rs 305 tbi

automatic....

 

Just as a double check the ALDL port on this car would be under the dash above and in front of the fuse box. Drivers side, far to the left, almost hidden.

Else pick up pin A8 on the ECM. Passenger side up under the dash on a velco'd slide mount.

i ran otu and checked under my dash and got pics (came in and read your post where itm ight be hidden...)

anyways here some pics:

would this be supposed aldl port? doesnt look like what it did on my old s-10...



as you can see in this one reference yourself to the fusebox on the left...



heres my fusebox area is it supposed to be uncovered like that?




and HERE is the overall pic of what looks to be a major chop into my wires for the alarm?




any help would be GREATLY appreciated. all i can hope ofr is for osmeone to say that the firstp ic (the mounted port thingy there) is my aldl... *** i hope it is..

 

That is it.

 

Only if something to do with the audio system, then yes it could be cause for a deduction.

I got out in 95.. I saw no reason what fishtanks and neon had to do with sound.



Damn I miss the discount thru Fosgate.. lol

 

and all this time i thought i didnth ave one. jeeeeeeeeeez. wow. made my day man. i thoguht for sure thsta tuning this car was going to be a NIGHTMARE.
