I need a diagram for the big t helm sh 5000

Go on line to a company called HELM .So its Helm .com
They print the factory manuals for most of the big boys .with a Chevy you might need 2 but their 50 bucks a pop and you will be able to look up and thing about your vehicle and never to ask anyone again .

Then your going to have to spend the big money
at Helm.Com & purchase the factory manuals

I have done that for 50 years

Obviously the ONLY place for the harness is the dealers
parts dept

Helm.Com --- have to spend the big bucks for a factory
wiring diagram book or get just the part you need off Alldata
at a repair shop

Nothing of any value, ever was free, for vehicles

Have to spend the big bucks with Helm.Com &
get the Factory Wiring Book

That is why you spend the big dollars &
get the OE factory manuals from Helm.Com

You will need to go to a local repair shop
,that has ALLDATA & have then print the
part of the wiring diagram you need

Check all the fuses

Buy Owners Manual---Helm.Com

You need a factory workshop manual,for diagrams. You can not get those on the internet or free. Avail at ( Helm.Com )
Discribe the issues, and I'll look it up in my 2004 manuals,wiring diagrams and diagnostic service manuals
