Hi all,

I've found lots of online manuals but I'm not aware of any that are specific to a 91 or 92.

My problem is that my ECU is from a 91 and I would like to be able to use my voltmeter to test the connections to the ECU.

So, I don't need the whole manual, just the pages that shows the connector pins and the corresponding resistance/volt specs.

Any help would be appreciated.

 

They have them for every year If i had the 91 EWD I would get you the information

The 92 will be different.

 

Well, it could be different. I asked the dealership based on my ECu number what year truck is that computer from. He said it could be either 91 or 92. So yeah it's a bit of a shot him the dark but what I'm going to do?

 

Bump....looking for either a full 91 fsm or the page mapping the ECu.
