Ok,
I am posting this question in the Tahoe section since they only members that I know of that have installed the Automate AM14 are all Tahoe owners. I have read though the two threads on this as well.

FIrst, I am not very electronically inclined. With that said I am trying to install the Automate Am14. It says to take the violet wire to the OBDII Pin 1. Then I need to connect to a Constant 12v Power and then a negative wire. I know jlenkows said he took the power and ground to the DLC wires 4 and 16. Is he referring to the DLC as the same thing as the OBDII?

Just to get this clear is this the same plug, DLC and OBDII? The one right under the steering wheel where the Superchips plugs in? Sorry if the questions are ignorant, I just want to do this right.

If someone has other or easier ideas where to run the power and ground that would be great. Thanks in advance.

I'm almost be certain that the diagnotsic plug is the only input inside the vehicle.

biglg....you have a NBS silverado right? I don't suggest you go to the DLC(OBDII, I belive they are talkking about the same thing) for power and ground. If you blow the cigarette lighter fuse, you lose power at the DLC. If you pop the small access panel off the left side of the dash, I belive there is power and ground right there for you to use. If its not on the outside of the junction block, 2 tabs to pull it out, and I know they are on the backside.

Working on an '04 Silverado 2wd extended cab.

My wires for the Cig Lighter a pretty well melted and I need to get my diagnostic working. From what I have read it seems like I can just rewire the DLC (OBD2) into a constant power outlet close by. I have found some people talking about the Mid BEC. Any advice on doing this, explained for a child.

I don't exactly know what I am doing, but need to get this done. If there is an easier way to do it, I would be open ears.

Welcome to the forum...
I'd try to remove the 12v outlets from the circuit and that should clear the short unless its somewhere further down the line... the outlets should have a connection to the main harness somewhere along the line...
