I had a test lamp in between the negative battery terminal and the negative cable, then pulled one fuse at a time until the light went out.
When I park the car and pull that fuse, no draw.

Do you have an FSM (factory service manual) yet? If not you might want to get one. I picked one up on CD on Ebay that wasn't too expensive. Once you've found the fuse you need to start tracing the circuit. I don't know off the top of my head which fuse is #1 but Book 2 of the FSM will show that. I'm surprised there wasn't a label on the block, did you look?

Hello there Gunn94!
I went to Harbor Freight and bought this device that I will include a picture of. It is wonderful for tracking down stuff like you are playing with. It is a digital ammeter connected to a plug to fit a 20 amp or the larger 30 amp limit fuse block like used in the auto industry. You simply plug it into any circuit and it will show you "Exactly" how much current is flowing through the fuse circuit. It helps me pinpoint little loads here and there on my battery. The device looks like this:

I apologize as I have not figured out how to make the picture a bit smaller, any ideas...help....
This device cost a whopping $15 for each model. I have the 20 and the 30 amp versions and have used them enough to justify them many times over. For tracing circuits it's great, I have used to verify actual loads on New add on circuits I have put in both my Corvettes over the years.
Keep us posted regarding you finding the current leak in your system.
Best regards,
Chris

IF you OWN a Corvette you need to OWN a set of the Factory Service Manuals. As the person above mentioned they are available in many formats and some are just plain ridiculously expensive. The factory set for my daughters Camaro was over $475 from HELM. I ended up buying a DVD on Ebay with The entire Factory Shop Manual set on one disc for the Camaro. Less than $30 for the disc and shipping.
For my 1988 C4 it was $90 it is not too bad to have the nice set of manuals from GM. It varies from year to year!
