that's also assuming a properly working tech2, the clones have the voltage defect, using a dc power supply is a easy work around, you really only need it if you are programming a module or doing a evap test, etc normally just for reading codes or troubleshooting it's no dig deal.
Sorry! I didn't intend on hijacking the "What I did to my NBS today" thread and turn it into a Tech 2 discussion!

Maybe the guy on Youtube didn't actually follow the directions. He plugged the AC-DC power supply into the DLC, where the Vetronix manual shows use of that power source from the house goes direct to the port on the Tech2 instead of the port on the DLC cable.
Vetronix did want direct 12V power from the car to go into the port on the DLC, but the house one goes to the Tech 2.

At some point, I will be using it for an EVAP test. So, not rebooting will be nice. Probably good to go, if I just plug into the port on the Tech 2 instead of the one on the DLC cable.

I am thinking that there is an upgraded power module for inside the Tech 2, too. I don't have time to look for it right now, but I think Dr. Shock may have a video on what to buy and how to replace it. Might be someone else, though.
there is, but to replace it involves a lot of work I ordered one and it's still sitting here untouched. lol

that evap test is difficult, for me it was atleast, involves timing things just right and holding idle at 2k for a period of time I gave up trying to do it pita.... if you even go off the idle parameters a hair it fails to complete the test and then you have to start over and by then it's not cold enough so you have to wait, grrrr
it was easier to just replace the part, problem solved

Did the high beam/low beam mod today, grounded the yellow wire on each low beam with a nice little heat shrink eyelet. That should be a major improvement.

Also spray bombed a crappy spare grill I had (off a parts truck that the PO had spray bombed the whole truck.... poorly) to see if I want to switch over to the black grill. Thinking I'll like it. We'll see once it dries.

Same as mine. I want to say model year 2003 was when they ditched stuff as well as changed the communication bus for the various modules.
Mine’s a 2003, and I have the light-up markers in all 4 doors, but no footwell lights. -That was I believe my very first “mod”, after replacing some other items like broken OEM headlights.

What’s the “high beam / low beam mod”? I took the easy route, and installed a fleece all-on module, which allows lows, highs, and fogs to all be on at once when using high beams. Is that what you did?

grounding the low beam to the body allows the highs and lows to remain on when the highs are switched on, easy mod for 00-02, not sure if it works on 03-06 they made some changes. I had my 00 modded for 6 high plus 2 more fogs I added for a 8 high lol
