Mack Superliner Wiring

Hello all,
I am doing a resto on a 1988 Superliner and am in need of a wiring diagram so i can nut out the bee hive behind the dash.
i have the basic r model diagram but it is fairly basic as my truck has the full gauge and switch cluster.
Any help would be appreciated.

Hi, pop the hole lot out and toss it. get a wiring Harness from Armadale Auto parts and do a full rewire. there for hotrods and work real well. mine has done 47,000kms now with 12 gauges.
Talk to Allen and tell him you want a 20 circuit harness as whats in my Mack.
if you get stuck I am just around the corner behind Auto One on Champion Drive kelmscott.
