I'm only going by your avatar for what kind of harness you are shopping for, so I just wanted to remind you and let you know that the Suburban dash harness is different than the pick ups (and more expensive).
There is a large harness that comes off the fuse block to feed the rear half of the Suburban. At the time of my purchase (few years back) M&H was the only company making a Suburban dash harness, and rear harness that runs the length of the Suburban up the A pillar and along the roof.
