Truck Repair: heater box visual, salvage yard, tritan

Question
I have recently aquired an 89 jimmy 4x4 and this poor truck has been butcherd in the electrical and the vacuum heater controls and I could really use a visual of the heater box with decent clarity and maybe in color ( graspin ) thanks for your time

Answer
Sorry tritan,
I don't have one. But if you go to the public library, in the refference section, they should have the shop service manuals, as well as Mitchell, Chilton, and Motors manuals for that year and model, and you can make some copies of the pages you need.

A trip to a salvage yard may also be helpful.
