CJ with wiring woes

I have a CJ with a steady drain on the power. The wiring is 95% Stock.

I have a 2.27 amp drain on the battery with all the fuses and relays pulled. I have completely disconnected the Alternator and the heater and Spedo cluster. I have disconnected the tank wires at the tank and the wires on the trans. (net. start and back up).

I have identified that the main red wire going into the Wiring block at the firewall is the 'offending' wire. I am unsure what else it could be.

I really hate to disconnect the square block from the fire wall on the back of the fuse panel. I have heard this is a nightmare once removed.

Has anyone seen this or have any suggestions?

I have taken mine apart before had to remove it to get the clutch petal off. just tow bolts than it come apart. maybe you have some crud shorting out between the tow block pieces.

didn't see starter in there as disconnected... check the lugs on them? What about bad solenoid?

On my motorcycle it was a bad voltage regulator. I know you said you disconnected the alternator, and I am not sure on CJ engines, but my 78 LTD had a separate voltage regulator that was also prone to failure.
