///M3 & Z

Would be pretty amazing to see this done. Would haveto warn you about potential costs though. Im coming from the BMW world and these engines are rediculously expensive to mod. Not kidding dude even just a set of aftermarket headers for this motor costs over $6,000! im currently putting an rb26 into my 71 240z and im amazed at how much cheaper rb parts are than m3 stuff, i would guess its about 1/3 the price for amost all the parts iv had to buy so far.

Hey been using these wiring instructions so far to prep the harness on my rb26 for my 71 240z but it seems like there are definantly some differences. I do not have those 2 big plugs going to the body harness, insteaded i have these 4 smaller ones. I have traced (pin 18) fuel pump relay, (pin 43) ignition switch start signal, (pin 32) monitor check lamp, and (pin 7) tach speed signal to the connector that I have circled yellow. I searched for the following (pin 45) ignition switch, (pin 28) engine temp sensor, (pin 58) battery power supply, (pin 109) injector power supply (small wire) and these wires all lead past the grommit into the engine bay without going to a body harness connector. All of my individual ground wires lead to the brown relay and then through the gromit into the engine bay instead of to the body harness. Would I be able to just splice into these wires and run them into the car to connect to ignition? would i be able to do the same for the individual ground wires? I also can't find the Air regluator wire and Power wire for the vct & aac on my pinout. I see 1 thick solid red wire going to one of the smaller plugs ( labeled on picture) however i am only guessing if this is the injector power wire. my pinout shows (pin 109) injector power supply however it is a small black wire being spliced into about 4 or 5 other wires. Would like to add that i have a complete r32 gtr parts car that i am pulling the parts from so i do have the complete body harness and alternator/trans harness aswell to reference too if that would help. Any help would be greatly appreciated. Thanks, Kevin
