Electrical problem solved 97 blazer (for now) LOL!

Problem: Stalled under all conditions. When you go to start it...turn key, no lights on dash and now fuel pump sounds. accesories worked lights, radio what have you. Under these condition blazer did not start.

Fix: Replace ignition switch. black box below ignition cylinder. Not an easy project but doable.

Still need help with a bit of wiring...when you remove old wiring harness there are 4 wires spliced in to it. They appear to go to the box just under dash down towards left foot. I think this is the keyless entry wireless receiver.

Does anyone know about these wires? Truck started with out hooking them up to new wiring harness but its all still sitting there waiting answers and I don't want to run blazer till I know that it can run with out this connection being made.

Thanks and good luck to all. TS
