The cigarette lighter under the dash and inside the console both have power.

Ok this Buddy as I forgot to pay my yearly dues oops

As for your OBD connection you said your fusses are good ok then you have a bad connection from your 7.5 fuse to your OBD 2 connection this wire is solid black and supply's power when key is on so look at your OBD plugin and find the black wire be in #16 slot this will be the one that powers your scanner

We have power to that wire pin #16 and chassis ground now we are chasing a ground fault on white/blk Pin #4 wire between the fuse panel and the OBD port. That is where we think we are losing the ground.

Someone had intentionally cut three of the wires to the plug.

 

Question is why would anyone do that? What would be the purpose of that?
