I am swapping a B18CR into a 1990 LS. I did a hydraulic conversion for my clutch. I am also running a OBD0 to OBD1 wiring harness and running a P28 ECU. I need a little help on what I should be using off of my LS block and where some of the plugs from my LS harness should go on the new B18CR, such as a plug that has 2 female plugs that used to go on the back of the LS block, I see no spot for it on my new motor. Also 2 more plugs on the IM.
