What did you do to your NNBS GMT900 Tahoe/Yukon Today?

Just noticed the part numbers, one is a -A and the other -B. Wonder what that's about..

Probably should be a D- and F…

You referring to "MIL" eliminators? Basically a resistor with a male plug on one side, female on the other, heat shrinked together that just plugged inline with the rear O2s when running no cats to fool the ECM?

I used to run them on the 02 mustang and I still have them in the garage, lol

Ah, yes, I remember them being called that, specifically for the Fords. The way mine worked, the PCM needed to see a varying signal so simple resistors wouldn't work. It was 20+ years ago, but I think the site had a universal design with instructions for connecting it based on car manufacturer and/or number of wires. Small black box with a red LED that illuminated during the "+" wave. I had a 4-wire O2 sensor, so I left the sensor in place and the heater wires connected and just tapped and spliced for power and signal. Soldered and heat-shrinked. To my knowledge, it's still doing its thing to this day.

Took it 86 miles to my friend's house in Kenner, parked it and took her car to the show. Took the Hoe to brunch this morning then came back home about an hour ago.

It'll be time for the 225K service in a few hundred miles.

Got a replacement set, a -A and -C. The new -A looked fine (like the -B and -C)
Maybe the letter is 'inspected by' or something similar..
They seem identical (tooling marks) so I think they are all from the same factory..

Yeah, I really consider the location and surroundings any time I park in public. She doesn't live in a bad area and she's right off a fairly busy street, in a curve before a controlled intersection. So, most people are whizzing by, watching the curve and for the traffic light and not casing the houses. You have to watch where you're going with all the cars parked on the street. She and her coworker roommate are federal DEA agents. They park their personal vehicles in the carport and driveway. Their OGVs are blacked-out SUVs with obvious strobes mounted in and on 'em. They're both parked on the street on each side of the driveway entrance like gatekeepers. I backed my Tahoe up under a tree on the side of the house so it's way off the road and mostly concealed to passing traffic. I feel pretty safe with her property and my Tahoe being guarded by two "cop cars".

Not too far away! She's on a street near Loyola.
