1967 C10 Parasitic draw

[Pinkdubai]

I have been chasing a parasitic draw on my1967 C10 project truck and hoping the forum may have some ideas to chase. The battery drains over a few days and requires recharging. I did review prior posts on this issue, which helped me get to my current state.

Here is what I have checked so far. Reading between negative post and cable is 1.20 amps. If I disconnect the red hot wire from the battery to the inside fuse box, then the amp drain is eliminated. As a result, I started looking for short circuits inside the cab. I removed each of the fuses to try and identify the problem circuit with no change in AMP reading. I unplugged the headlight, and wiper switches with no impact as well as the brake switch.

Appreciate any thoughts on how I can chase down this issue.

Thanks,
Lance
