So the black plug has a home but the 1 with green/yellow wires is still homeless? Is the fuel pump working yet? Do you have old harness? Is there the same wire/plug on old harness?

Its green and black. And no, pump is not working yet. But I looked on the fender where the relays are. And the new harness only has 2 where the old has 3 so im guessing that might be the issue now

When you say new do you mean new or just replacement used harness?

They should match up perfect. The blazer was based off the s10. All I bought was the engine and transmission.I'm guessing when I bought it it didnt have 100% of stuff included. Anywho how would I install the relay and wiring?

Could you explain exactly what the project consists of altogether? Are you installing a motor and trans into a vehicle and the wiring that is in it already is not matching up? Thanks
