Junction Block SEO Connector For 1999-2006 Chevy GMC – MBEC – OE 12193930

If you’re doing an upfitter install or chasing down an electrical gremlin in a 1999-2006 Chevy or GMC, this is that little junction block connector you’ve been hunting for.

It’s the MBEC SEO connector, also known by the OE numbers 12193930 and 12191479.

Brand new and ready to plug in, it handles the auxiliary power and upfitter connections.

Universal fit?

Nope—it’s specific to these GM trucks and SUVs.

Just a heads-up: it doesn’t come with installation instructions, so you’ll want to have a wiring diagram handy if you’re not familiar with it.

Solid little part from automotor2020 with a 1-year warranty.
