hey Im starting to wire today. And Nismo241 has sent me a little bt of info that I summed up as this...1.) Locate the 2 rectangle plugs (6&8 pronged) on the RB engine harness. 2.) Locate the 2 plugs (BROWN & GREY) on the on the 240sx engine harness. Near the battery. I think they are the E10-brown and the E9-Grey3.) Will splice 6 wires from the RB harness INTO the 240sx harness. 1. Ignition switch 2. Main power 3. ECU power 4. Fuel pump 5. Starter 6. Alternator
For got to mention : rb20det into a 89 coupe. The thing is...I got a s13 service manual of the net and traced the wires coming from the E9-E10 and some are right but one goes to the Air Conditioner Relay?!? What's up with that?
starting the wiring....

What manual do you have?
I'm thinking the KA24E chassis harness is NOT the same as a KA24DE harness. Both are in the S13, but not interchangeable.
I have the '92 240SX Nissan Service Manual. Just ordered a R32 manual from Oz, should be here in a couple of weeks. Ya, I'm a little to anal about documentation.
I'll be dropping a RB20DET Auto into the '92 240SX.
Does anyone have a supplier of OEM style connectors? On my EFI conversions I've stuck with Weatherpack (GM-Delpi) stuff, but would like to find OEM Japanese style connectors. Ya, PITA... but nice to have everything like super clean.

Where are you?
Just wondering as we didn't get the RWD 200SX here is the USA (its a FWD Sentra badged 200SX in these parts i.e. B14 if I remember correctly).
The factory manuals will state "Nissan Motor Corporation" on them. LOTS of variations on wiring harnesses depending on years and market.
You might want to "confirm" the function of the wiring before getting too far into the swap.
NOT SURE on the R32 ecu's.... but some ECU's are fault tolerant of pins being shorted to gound, others are not (and damage the Integrated Circuit) in the box. Sad part is most IC's are custom for the OEM manufacture... pays to spend the time and confirm everything is functional before powering it up!

No problem.
I really prefer the FSM (Nissan) as they will have the best information on specifics like the wiring harness.
The later Chilton's improved, but they will contain 50 million wiring diagrams. Problem is they will not be correct in all cases. I wouldn't put it pass them to state '89-97 240SX wiring diagram, yet it is only covers '92-'95 automatic's.
Alas, 25 years ago I LOVED Haynes manuals for being good common sense manuals. The Datsun PL510 (FSM) manual would state "remove seal using tool #xxxxx-xxxx" The Haynes manual would have "use a screw driver with a bent tip and yank that seal loose". Chilton would show a picture of a V8 Chevy engine and no seal! :rolleyes
Sadly the Haynes manuals seemed to get worse in the 1980's, Chilton's improved (yes, pictures of the actual vehicle!), but the Factory Service manuals are hard to beat.
You do need to use common sense on their "trouble shooting" diagrams... as those diagrams cover the most common faults (i.e. what happens 90% of the time when you see this error). Quite often you get to the end of the trouble shooting diagram to only discover "replace ecm"... catch is the ECM was fine, but when you noticed a bad TPS (reading too high)... and started to trace it, you discovered a bad horn wiring back feeding 12V onto a line that should have only had a 5V reference on it.
I've since "retired" from automotive wiring stuff, but enjoy the challenge of things that are normally unsolvable. Ya, still help out a buddy who owns a shop, but by the time I see something it is really strange!

Roundrocktom, where did you get yours?
Any help would be appreciated.
