Anybody have a picture or URL for the fuse diagram for a 87 pickup?

I'm sorting out a parasitic battery drain , and I need to know which parts my fuses correspond to. I don't have an owners manual, but I'm assuming that's where this info would be. Anybody holding?

Do you have an aftermarket trailer light kit or radio? I can almost guarantee that's where your problem lies.

I did install some Hella 500 aux lights on the front.

However, after the drain I removed and recharged my battery, and reinstalled the battery without the wire from my aux light relay running to the + terminal. That should negate the aux light's ability to draw power from the battery, right? Battery still drained after probably 24 hours.

Do you have a multimeter circuit tester?

Yeah, I'm planning on using the multimeter, set to amps, connected between the - terminal and black wire, and start pulling fuses one by one.. This is the process I read about in a previous thread, located here:

But, assuming I figure out which fuse it is, I have no diagram to show what the fuse corresponds to.

Anybody know if the owner's manual has the fuse diagram, or if not where I can find it?

On my truck it's not inside the panels that conceal the fuse box, in case that's where it usually is.

There's a scanned FSM for an '89 at this link:
