I am attempting to get an 88 F350 electrically debugged and my cheap wiring diagram is just no accurate enough.
Anyone got a real shop wiring diagram for the 88 F350?.
I am looking for grounding points and such.

 

If they still have them in stock, you can get the real factory diagrams from Service Manuals, Owner Manuals, Wiring Diagrams, Service Bulletins - Helm Incorporated

What's the problem? I find that it's easier to add grounds instead of hunting down the factory ones.

 

I went to the Helm site and ordered what wiring info they had on line for the 88 f series which was the electrical and vacuum ts guide.
Thanks for reminding me of Helm.
Some issues with dash gauges and lose unconnected wires that I want to resolve.

 

I think that the AUTO ZONE web site has the wiring diagrams on there for your vehicle....and they are FREE!

 

The 88 diagrams on Autozone's site are lousy. They are ok if you have nothing else, but they just hit a few of the circuits like the engine, headlights, sometimes the electric windows, it's hit or miss. The Autozone diagrams really get good though starting around the 2000 models and up to about 2005.
