Rb25 wiring question, need clarification

[240slidekat]

ok i was labeling my wires so when i do my wiring i wont have to search too hard. my question is #1. i was looking at step .10. on this wiring instruction posted below and it confused me a little bit. i looked at my ecu pin #7 and there is no pin or wires on it. Also on the so called "RB white plug" there is only one yellow/lavender wire on it. there is two yellow and blue wire though.

#2. Also where is this RB grey wire (af81 injectors) at? described on step .4c.

#3. And are we simply using the redwire taken from ka injector wires in step 8 of "kade and transmition removal" to connect af81 injector wire to the af36 ignition relay?

#4. and one last thing what does RSM stand for in steps 12 and 13. thanks and sorry for the long post. Just trying to clarify some things.

· 1. Attach twin power connector to positive terminal. It’s the red plastic connector which will power the engine room and dash harness. Also attach the RB lower engine harness to the positive terminal (from the alternator, starter, etc.)· 2. The RB harness’ white main plug (B-82) has been cut off close to the bundle. Cut all of KA wiring harness that will be used at the ECU plug. All wiring connections will be done at the RB wiring bundle close to the ECU inside the car. I will refer to this as the “white plug”.· 3. From the brown KA plug under the dash above the ECU, connect the Orange wire (#34 Start Switch @ ECU) to the RB white plug Grey/Red wire (AF09 Start Switch).· 4a. From the KA ECU plug, connect Red wire (101 ECCS Relay) to RB white plug Red wire (AF04 Ign Relay).· 4b. From KA ECU plug, connect Black/Red wire (#36 Ign Switch Fuse) to RB white plug Black/Red wire (AF36 Ign Relay). Get this B/R wire from the KA wiring harness. Refer to step 8 of “KA24de and transmission removal”. This is the wire that was cut at the KA injectors.· 4c. From RB connector A-? , need to connect RB Grey wire (AF81 Injectors) to the B/R wire connection in step 4b (AF36 Ign relay).· 5. From KA ECU plug, connect Black/Pink wire (#104 Fuel Pump Relay) to RB white plug Black/Pink wire (AF73 Fuel Pump Relay).· 6. Break for a beer.· 7. Connect main battery ground wire from the RB engine block to the chassis.· 8. RB lower engine harness olive plug, connect the Black/White wire (Starter Ground?) in this plug to the Black/Yellow wire from the KA Grey plug at the bottom of the fuse box near the battery location. This is the only thing to connect in the engine bay in this 8 step wiring. Continuation of Wiring:· 9. RB white plug Red/White wire (AF10 Check Engine Light) connect with KA ECU plug Red Wire (#24 Malfunction Indicator Lamp).· 10. RB white plug Yellow/Lavender wire (MF01 Tachometer Out [#7 on ECU]) connect to KA ECU plug Yellow/Red (#2 Tachometer) and RSM Yellow wire. There are 2 Y/L wire at RB white plug so make sure you attach the right one.· 11. RB white plug Yellow/Green wire (MJ04 Hicas Diagnostic Wire/ Speed Limiter) connect to KA ECU plug Yellow/Green (#32 Electronic Speedometer) and RSM Pink wire (connect close to ECU) and Purple wire (connect distal to ECU). Note: Speedometer on RSM is km/h and mine is completely inaccurate. I am using my KA electronic HUD speedo in km/h and it is 10 mp/h off. · 12. RB ECU #59 Black/White connect to RSM Red wire (Ign Power).· 13. RB ECU #50 Black connect to RSM Black wire (ground).Note: steps 12 and 13 you can actually connect at the RB ignition relay. That is one of the 2 relays located close to the ECU.· 14. Check the wire color for the engine temperature gauge at the back of the KA gauge cluster and connect it with the RB temp wire. Sorry, did not make note of the color.

follow this and jsut repin the f3 plug and give power to the grey injector wire and you're done.

i can help with #2 as i had a hell of a time with it and jons ******* and vague replies.

the grey wire is the one in the engine bay. it is in the connector that branches out to give signal/power to the injectors. it is right infront of the intake manifold and slightly bellow it. also it connects to ground. not +12v.i clerify that because when people say power it sounds like its supposed to go to possitive. when i tried possitive not even a noid light would work, when grounded it lights up very nicely.

So is it that gray plug with the gray wire in front of the intake manifold? this picture right here

[Valley]

correct, the one with 7 wires going in, it should be the upper plug. the lower only has 6 wires going in.

so what does the abbriviation RSM stand for?
