i have a good 96 civic that had a hx motor in it i did a z6 swap i got the car running but I didn't like all the extra wires and jump harness so i purchased a harness from sjs wiring bolted it in and now i have no fuel no spark cant get the check engine to flash codes i tried to work with seller and got really no help its been sitting in my garage for months
he kept telling me to jump the fuel pump but with the sub harness i cant figure out which wire to jump any help will be great

 

Also once i installed the new harness the fuel gauge doesn't work now
