Ok so i have completely tore 3 jeeps apart to make one jeep and i tore all the interior from one jeep and put it in my 00 and i took the whole wiring harness from the drivers side on my 03 and it all matched up but i dont have my seat belt wire and a sensor under the rear seats hooked up. Now do i have to get those sensors plugged in for my jeep to start cause my fuel pump does not turn on. or do i have to maybe add in the plugs into the harness to make it fire? we have spark and know that 100%.:sad :
