Factory Service manual in pdf or paper

I am looking for a 1989 service manual for my new Comanche I bough today, previous owner did a job on the wiring and I need to fix it. All help would be greatly appreciated.

1990 is the same as 1989 for most things. Every wiring diagram has been completely accurate including wire colors. for my 1989. Click on the one that says "1990 Jeep Vehicles"

Here is the 88 electric FSM.  Most of the wiring should be the same for 89.

Thank you Minuit!!! I've been tearing my hair out trying to figure out this dang radio wiring! Your link is a life saver! Quick question though. How do I tell which is postive and negative? (I was looking at page SJ 29 in the 1990s jeeps manual)

Without looking at the pages you cited -- in general, negative always ultimately goes to ground, and the wires are almost always black or black with a tracer. Positive wires are colored, or colored with tracer. To find out where they come from, you may need to jump from one page to another to see what's on the other side of a connector.
