i know im soposed to remove the box to use obd1 injectors, but how? ive read to unplug and solder the wires together, but that seems odd, to just solder 5 wires together as 1, is this how its done or do i solder them together seperatly by color?? and also will obd1 injectors just plug into my 89 si harness??
