OBD1 adapter
Gentlemen, I purchased a OBD1 to OBD2 connecting adapter so I could use my current scanner which I know works yet when I plugged it in to my 90 to get codes on the screen the scanner would not light up? I then confirm that my scanner would light up when I plugged it into my 05 as I have many times in the past.
My question to everyone is why does it seem the the OBD 1 plug on my 90 does not light up my scanner with this adapter?? Realizing got the adapter could be bad is there any other way I can confirm that my OBD1 plug on my 90 is not at fault??
As always I appreciate any input or advice!!

Thank you gentlemen!!
I understand that the OBD 1 plug does not provide power to light up my OBD2 scanner with a conversion cable from the OBD1 on my 90 Corvette to my OBD2 scanner?? Sorry to ask the same question twice but at this point am I to understand that the scanner needs power since the OBD1 plug on my 90 does not provide power? Again sorry to repeat but would like to confirm where power should be supplied assuming my conversion cable from OBD1 to OBD2 scanner is okay.
I have an actron OBD2 scan tool that works fine with my 2005 but if it needs 12 volt power to read the codes from my OBD1 90 Corvette what is the safe way to supply power to the needed source??
Again thanks to all for the responses and I apologize for the duplication of questions but rather be sure then create a problem as we all have experienced over the years.......

I doubt the Actron has any provision in the side of the case to supply 12V power source to the unit. So you will probably need to split the case open and solder a connection point in. Or you figure out the ALDL port on the OBD1 connector and supply power through there. Or just buy an appropriate tool.

OBD1 port does not contain a power wire like OBD2 port. The tech tools at the time that were being used, either used a cable going to the cigarette lighter or provided a cable that connected directly to the battery of the vehicle.
