Jason81NA,82RBtt Posted April 20, 2009 Share Posted April 20, 2009 I've already gotten a RB20DET installed in my 1982 280zx. I did the wiring myself a few years back, but the engine was pulled from a 240sx. I bought the car with a skip, turned out to be the ECU. Bought a Skyline code BH ECU only to find out my RB20 is from a A31 Cefiro. I have decided that I needed a new harness because if the current harness has been messed with too my for my liking and the A31 and R32 have a few different pins. I've bought a 1993 Skyline computer and harness. Before I remove the old harness I would like to find out what a few of these new plugs are. There is a large black greasey plug that went under the hood. What is this for? Then there are the two S13 style plugs that went to the R32's dash wiring.Does anyone have a pin out of these? Then there is a Z31 style(yellow clips) plug that has space for 12 wires but only had 5. What is this one? Thanks for the help as always.

Careless Posted April 21, 2009 Share Posted April 21, 2009 have you tried to lay out the wiring on the engine bay as it would be when installed? that will give a better indication of where the plugs MAY be located. Quote Link to comment Share on other sites More sharing options...
