Apexi RSM - G Sensor Wiring

[michael]

I've finally overcome my phobia of wires and feel ready to install my RSM and G-Sensor, mainly because I've realised it splices into the same places as my AVC-R so I should be able to use that as a guide

 

Anyway the only bit I'm wondering about at this stage is the G-Sensor.

 

It has a number of wires with a small plug on the end, these go into the bottom of the RSM unit itself, that's not a problem. In addition to these there are 3 short wires coming out of the sensor, a purple one, a white and a black.

 

My install instructions are in Japanese:

So firstly can anyone read that?

 

If not can someone confirm my thoughts that these wires need to splice into the same coloured wires on the RSM harness?

 

The instructions with the RSM are english but only explains the need to put 4 wires into the ECU - Speed (Purple), Ground (Black), RPM (Yellow) and IG Power (Red) - this leaves 4 wires on the RSM harness - pink, white, blue and grey.

 

So if I wire the G-Sensor up to the purple, white and black as I suspect that still leaves pink, blue and grey - these are indicated to be:

 

Pink - Speed 1 Output

Blue - Speed 2 Output

Grey - Another Output?

 

I know you can set the RSM up to output if speed or RPM reaches a certain point (I'm hoping to set up an LED on the dash as a rev warning light with one of these) but that still leaves one unaccounted for.

 

Can anyone advise on any aspect of what I've just rambled on about or point me to an idiots guide in English?

I should have clarified that I have the RSM instructions in English (same as those linked to) and that part of the install is OK with me, they just don't mention the G-Sensor install beyond actually using the unit with it.

 

You get a leaflet with the G-Sensor itself, that's the one that's in Japanese.

Give James G a shout, as I believe he has one installed by himself.

Cheers Nick, I've uncovered the AVC-R wiring so I'll wire the RSM in using those as a guide tomorrow, the RSM plug might be the only thing I need to use if I'm not taking external inputs so I'll plug it in and see what happens

 

Just need to decide what the best way to splice the wires togther is, I'm feeling brave so I might get the soldering iron out

The extra three wires don't do anything, you don't need to splice them anywhere. I think they are for use with a different bit of kit. They aren't connected to anything on mine and it works fine.

I now have an RSM with G-Sensor, my fear of wires has been overcome

 

For the record (and future searches) the wire colours on the AVC-R and RSM are different, live and ground are the same but the RPM and Speed signal wires are different colours.

 

The G-Sensor just plugged in without the three wires being attached to anything.

 

I haven't been out to play with the RSM yet but it's all setup and calibrated ready for the morning run to the office.

 

It's been a constructive day, I missed Japs at Ollerton but I removed a Nokia car kit, wired my Origin b2 in properly, emptied my glovebox and sorted the RSM out - I'm happy
