First off, the tech2 will only tell you the fuel level if your cluster is working, the menu for that is under instrument cluster and if you have no communication with it, no fuel level.
But I wasn't driving it anyway. So today I got the new used cluster. I plugged it in, nothing. damn. I started thinking maybe the BCM was damaged after all. I have a new one here ready. But I decided to see if it was a ground issue. I had checked battery and accessory power but not ground. so i rigged up a jumper and stripped a bit of the insulation from the ground wire at the cluster band connected it. Still nothing. Then I was checking the power at the connector at the back of the cluster and suddenly the acc power went away. I looked closer and the wire going to that pin was only held on by the plastic insulation. I tugged it and it came right off. AHA! It must have been making contact when I pushed the test light in and when I wasn’t pushing in it, nothing.
The new cluster had come with the original style connector and I really wanted that type of connector anyway so I replaced the one that could go on backwards with the correct, keyed one that locks in place. That took awhile but I got it done and checked to see if the cluster worked now. success! then I checked the original cluster that has the correct mileage. Success! I was winning but I kept thinking something is gonna go wrong, remember
@iamdub nicknamed the truck 'the period" because it's an emotional rollercoaster. But it was going soooo good. I swapped out the bezel because my original was pretty messed up and the clear part of the lens had a crack that always bothered me. I went to put it in and found out I needed to trim part of that bezel for it to fit. Done. then I went to screw it into place and it wasn't going back in the hole far enough. It was the new connector- it sticks way out. But it looked like plastic that I can just trim out of the way so out comes the Dremel again. Cut the plastic out and...it's metal behind that. I tried it again but it's still not fitting. So now I have the decision to make- try to cut or smash that metal back or replace the plug with the ****** one. I had to quit, the roller coaster caught up with me.
