Having a '98 I figured you'd know the ECU is under the hood, not in the cab. Only 94/95 had the ECU inside the truck.

 

Never having messed with it I see now that the copy of the manual is for a 95 hence it showing the location as behind the fascia below dash. So then I assume my ECM is behind the cover on the wheel well next to windshield washer tank?

 

Yup just waiting for water to get splashed in off the tire

 

had that happen once. getting towed out of a river is fun, then ten minutes later the truck starts like it is nothing.

 

Tried some CRC Wire Dyer, It was recommended to me in a post on one of my threads and it works great.

 

Yeah that's the dumb thing, I have swam the truck deep, no issues splash puddle and dies a few minutes later oh well

 

In aviation we use a lot of acf50 it's great stuff I plan on treating both of my rovers frames with it. At the shows they will treat a tv let it dry and let I play inside a fish tank with water.

Why is it only effective for 24 months

 

In aviation almost everything has a life-limit most is just CYA. The acf50 will last much longer, but the company dose sell product and in makes more profit the more it's used. Acf50 will move/creep for 6 months then dry to a light varnish. Corrosion x basically never drys but forget painting any were its been applied. Boeings T9 is close to the same but with more wax in it. I prefer acf50 do to the fact it will stop moving and form a protective varnish and I don't come out of the hell hole all oily the next year after an inspection.
