I downloaded WINALDL, and built the cable as shown on the website, but when I went to plug the wires into my aldl underdash plug, I found out that my '93 Chevy truck's plug is arrayed differently than the plug shown on the winaldl site.
Specifically, I have no "E" terminal prong on my plug - just a hole.
If 0's are empty holes and X's are holes with prongs, my plug is arrayed as follows:

00X0XX
XXX00X

Anybody have any ideas on how I can get this to work?
Thanks,
SC

 

You might try to find out what the guys running '90-'92 TPI are using as far as terminals go. Same ecm as yours and both are sd systems. I'm having the same problem with my buddies '91 z as far as finding what pins to use. Somebody did say something about using a total of three wires though, so the cable you have may not work. You may need to add a resistor as well. I know we put the ground in terminal A and tried the other wire to every other terminal to no prevail. Anyways, if you find anything out, be sure to post it. Good luck

 

I talked with JW at customefis.com and he told me WINALDL will only work on '93-up trucks that have a manual trans. If you have a 4L60E - like mine- it will not work. He told me I would need to run the Datamaster program from ttspowersystems.com inorder to pull data from my ECM. I'm going to give it a try. SC
