I have a 1995 LS b18b bottomend I just swapped a 1st gen b16a head onto.I have a GSR ECU and wiring harness but I knwo realize it's not going to plug up.I had originally thought I could use GSR TB,INJECTORS and DIstributor.Harnes is a bug mess I also have jdm b16a harnes along with usdm ls harness do i need to combine these for each sensor from short block to head?What about the obdo head with the newer ecu.Please a little point in the right direction would help(ie.website or instructions,ect..)thanks
