Default "95 w/OBD 1. Pulling codes

I have done a search and seem to be getting conflicting information on pulling codes out of a '95 Olds 88 with a 3.8NA and OBD 1 and the "newer style" diagnostic port. The emissions decal says the car is OBD 1. Some fellow benchracers tell me I can ground 5 & 6 and get trouble codes the same way I do on my '90 Chev. But none of them want to ante up if I fry a module. Is this possible or should I trail down to Auto Zone/ O"reillys and have them scan it? I know eventually I will get a scan tool but thats a few paychecks away and I would like to get rid of the pesky CEL.

1993 was the last year that you could pull codes with the jumper on the Bonneville'*. I be guessing that it is likely the same on the Olds.

Good News and Bad News.

Good News - You didn't listen to your fellow bench racers and therefore didn't damage anything yet.

Bad News - Your local AZ or Advance will likely not be able to help you either, since the '95 is a bast**d child and requires a scantool capable of reading OBD I codes, but adaptable with the OBD II connector. I'm going to take a stab at my memory and recall that the Actron CP 9145 with adaptor cable or the CP 9150 kit are the most likely answers to your troubles.

Option: Pony up the $45-50 for a local mechanic'* shop to read the codes for you. A plus with this method is the opportunity to chat about possible causes and fixes for free (IF the shop is reputable and they like you....lol).

Hint: Look on eBay for one of the Actron scantools mentioned above. They sometimes can be had for a decent price used.
