where can I get a free wiring diagram for my 88 econoline?

In need of help!!!!!!

I am having alot of trouble diagnosing the drain in my e-150 waldoch conversion van. It has the 5.0 302. If someone would be willing to scan a page out of a hanyes mannual for me I would greatly appreciate it. You can e-mail me at superbeatle1973@yahoo.com I'am currently taking my alt. to be checked, but I don't think that is the problem. I need to know which circuts should be hot with the key off? Also need to know which fuse is what. It has 2 fuse boxes by the brake pedal.

Thank you for your time.

I am also curious to know where that I might find a lowering kit for it also?

I FOUND THE DRAIN on the 7th of Oct. It is an internal short in my jvc khameleon CD player one channel isn't working right. I found it using a make shift test light between the positive side of the battery and the positive battery clamp. Then by pulling fuses one by one and shutting the door. To see which one would shut the light off. (All of this while the van was not running and the key off. Shut the door to close the circuit for the interior lights.)
Once I found the fuse I tracked it down to the radio, One speaker didn't sound right, so I checked the speaker by hooking it up to another channel, it was okay, I ended up replacing the fuse and unplugging the radios' harness and the light went off again. The battery hasn't drained yet.

Steps to find a short!
1. Connect a test light between the positive battery post and
the positive battery clamp.
2. If the light is on, even barely, there is a short. (If not there is
no short.)
3. One by one pull out a fuse then check to see if the light went
out. BE SURE TO SHUT THE DOOR EACH TIME!
4. Found the fuse! What ever is on that circuit could be a
possible drain. Could be: a loose wire, rusty ground, melted
wire, faulty equipment, or corrosion.
