If you ain't first you're last
A short in the wire probably, check the wires running to the fuse and to the computer

Make sure there's no frayed wires grounding out and check the grounds on the truck too

i put on valve cover and upper manifold gasket. plugs,wires,coil pack.
anyhow got conecctor unhooked to tranny and it drove just fine, but of course no OD.

I had this problem with my 91 a while back. Turned out when I changed the transmission filter a long time ago I got the overdrive solenoid wire pinched between the pan and the trans case when I put it back together. It finally rubbed through the gasket and the the wire shorted to the trans case.
