wiring diagram
 

New to the group, looking for a wiring diagram for the engine portion of the connector that goes to the firewall on a 1993 jimmy 4.3. did a 5,3 swap and that portion of my harness got thrown (daughter helped clean the garage) Any help would be appreciated, i got the bulkhead connector from parts yard but wires are cut thanks in advance for any help

Can somebody confirm that it will be the same as a 1994 CHEV?

I have the electrical manual for the 1994 but we should confirm the compatibility.

PM me if you are interested in the manual pages on that connector.

Could use any help I can get thankyou

it will take a day or two. being busy at the moment.

o.k.

we have to nail it down.

What blazer used that to be? Pickup? Utility?
What injection did the engine originally mount? TBI? (IMHO should be the TBI)

The electrical and diagnostic manual has about 80+ pages on the various vehicles.


Could you please post a picture of your connector and a picture of where that connector should be in the engine bay.
