I have a Chevy Sonoma pickup truck, blue. I was putting on new sparkplugs and sparkplug wires. You guesed it - I didn't keep track of them now I don't know the order they have to be. Does anyone have a picture of their Chevy Sonoma spark plug wire configuaration that I can copy, or where I can get the exact schematics

Many public libraries will have Motor or Chilton's manuals in the 629s (vehicle section). Call your library to find out where you can access them.

4 or 6 cylinder?

Please, more not less...

At least tell us what year your blue truck is

It is a 1993 V6 Chevy Sonoma - Thanks

For a V6 Chevy S10, can't find Sonoma yet, If Distributor turns clockwise, firing order is 123456.
For Counter clockwise 165432.
A Mark on the distributor will tell which is #1.
Good luck

1-6-5-4-3-2
To identify which cylinder is number one, number one is the cylinder that is nearest to the radiator.

There actually should be a diagram on the hood underside.

Yes, should but they don't. There often isn't even a serpentine belt routing diagram any more...

I have seen the Firing order on Manifolds in the old days.
