Help! Wiring boondoggle, truck lost electrical power.

Gotta keep this short because I have to head into the office. Hoping someone here has some ideas…

I installed a @MESO 3rd brake light this weekend. It’s the BD5-NMO version and I initially attempted to run relays to the lights due to the keyless interference issue.

I got it all wired up last night and I started popping the cargo light fuse and brakes light fuses. Long story but eventually gave up on the relays and direct wired the brake light.

I drove to work and when I shut the truck off, bam no electrical power. No door locks, hazards, nothing. Battery is good for sure. Brake light 10A fuse is still intact.

Thinking it’s a fuse/relay somewhere for main power. Anyone know which one it may be?

I’ll need to replace that and disconnect the 3BL. Pending any other better ideas.

I have to run… hoping some of you have some good ideas that I can start working through when I can leave the office.

It’s dead, so I can’t leave until I sort it out.

 

Wires to LEDs need there own battery fuse feed (not Ignition/ACC source)
original wires to Cargo Lamp and Stop are the feeds/triggers to the relays.
