Ohjai Posted May 25, 2023 Share Posted May 25, 2023 I have looked in the manual and searched this site but can't find out where the ALDL connector is located. I have a TECH 1 and modules coming tomorrow and would like to play with my new toy, but before I can do that, I need to plug it in, and have no idea where to find the connection point. thanks Jim Link to comment Share on other sites More sharing options...
2seater Posted May 25, 2023 Share Posted May 25, 2023 (edited) On a 90 it is left of steering column under the dash, BUT, the 91 has a different ECM so maybe things moved, and it should have a cover over it that says "do not remove". Don't the onboard diagnostics work? Edited May 25, 2023 by 2seater 1 Link to comment Share on other sites More sharing options...
Ohjai Posted May 25, 2023 Topic Author Share Posted May 25, 2023 Thanks 2seater. Yes the onboard diagnostics work, but I have an ABS light on , plus I like to play with test equipment. I am a retired maritime mobile electronics service guy and like to look at meters. 1 1 Link to comment Share on other sites More sharing options...
