I was wondering what all I will need to get off the 91 suburban for the efi swap to my 86. Will I have to change out the whole harness including the dash wiring?

Its would be a good idea and i should make life easier

Will I have to have a electric speedo or can I keep the cable operated and my cluster?

Id put it on it might effect the computer some how

Will the tank from the suburban fit the rear of my swb truck??

Not shure i know a blazer will

Would it be easier to use the complete sub harness so I can convert to power windows and door locks?

Always If you want to have every option the suburban has id take anything it has in wiring.

I am also converting to the 91 front end so will I need the whole headlight harness? Sorry so many threads, I need a lot of help

That a good one but if ur going to use the dash harness then yes use it cause it will mount right were it was in the burban and save any headaches that come if u mod the stock harness to match a newer harness.


Hope this all helps
