Here is the wiring diagram for your year of truck. 1987-1994 is the same (not including powerstroke direct injection, of course):

Top of the engine / under the turbo ... The harnesses are unchanged on the Turbo models!

Here is a picture that shows how the harness runs...

It's a little dark, it's a non Turbo motor, but they are the same, if it's to dark to see let me know and I'll get a daylight one.

The wires run accross the engine under the intake of the turbo. Do not run it like Fetus' picture, oops I mean Festus, They move the gp controller up onto the valve cover to keep the turbo from melting it I've seen trucks with the 088 turbos that who ever installed it left the GP controller were it was and it melted.

Pan, valve covers, front main seal, rear main seal, oil cooler O rings, Oil cooler gaskets, front engine cover, rear engine cover, oil pressure sending unit, turbocharger (if equipped), valley pan gasket.....

It really depends on where its dripping off. Ideally you would crawl inder the truck and try to trace the leak back to the source.

mk i'll take a look. becuase i tried going underneath but due to a lot of krud on the axle and cross member it is very hard to tell. I'm going to have to degrease it so it makes it a little easier.
