Customer Question

Hello, I need a wiring diagram for the plugs that plug into the back of the fuse panel, for a 1998 S10 Blazer 4.3 4x4 vortec. The pins were mixed up trying to wire it to a 2000 harness. There are 4 of them.
Thank you, Mike

The smaller ones are the same as before. I couldn't get you a complete diagram, but as you go, I can get you more specific diagrams for individual circuits if you need them.

One more thing you have been a real help. Is it possible we burned the ecm?

Expert:  Ivan replied 7 years ago.
It's possible, but I wouldn't worry yet, I feel you may just have some mixed terminals depriving some circuits of power.

Hello Ivan,

 

Thanks to you we got the engine running. Everything works except the headlamps.

On the green plug there are 2 sets of purple wires on my harness but on the diagram it only shows for one in b4. This vehicle has fog lamps I didnt see anything on the diagram for fog lamps. I put 12 volts to the one set of existing purple wires and found that the fog lamps lit up. Is there another diagram with fog lamps.

 

Thanks, Mike

Expert:  Ivan replied 7 years ago.

Excellent, would you like a diagram for the headlamps?

Customer: replied 7 years ago.

If you can please. will it show where the other set of purple wires belong for the fog lamps on the green plug?

 

Expert:  Ivan replied 7 years ago.

Start with these and let me know what you need to go along with them.

 

Ivan
