Truck is a 96 chassis cab, 5 speed 2wd. 365,000 miles.

The "engine control" (I think that is what it is labeled as) fuse blows the instant the key is turned on.

Does any one have a diagram of the pcm harness? I would like to ohm the wires to check for any short to grounds, before I throw a new pcm in it.

Any help, or other ideas as to what could be the problem, would really be appreciated.

Thanks.
