Hey guys, just joined, and I need some help. I am currently lifting my '95 blazer 4x4, and I am putting 31s under it. I've read that I have to do something to the VSSB, but I am unsure if I even have one. I found a little silver box on the passenger side behind a panel right next to the door. Would that be what I am looking for? Also, anyone know what code scanners or if dealerships can read codes on this stupid OBD1.5? I can't find anything anywhere, besides the occasional thread saying to jump pins 6 and some other pin on the port. The problem is that I don't HAVE a pin in the 6 spot. Any help would be greatly appreciated!

 

The box behind the passenger side kick panel would be the transfer case control module, TCCM. I've never heard of any need to modify it.

What is the VSSB?

BTW with 31s you may need to do some small trimming of the front wheel well.
