Topic: Bandit 400 dash wired into Katana 750 harness

[Scott S]

Working on a project that has Katana/GSX750F engine, suspension, etc, in a 1980 GS550 frame. I have '91 Bandit 400 gauges and idiot lights I plan on using.
I am now faced with mating the B400 wiring to the Kat750 harness.

The plugs are completely different. I have a wiring diagram for both and am studying what goes where. I will need back lights for the tach and speedo, a neutral light, oil pressure light, turn signal indicators and Hi-beam. I can forgo things like gas gauge, water temp, etc.

This the the Kat 750 plug.

This is the Bandit 400 plug (notice the single Black/Yellow plug, too)

 And here are some wiring diagrams.

 Bandit 400, with a close up of the dash wiring.




 And 750 wiring.



 There are a couple of wires I won't be using....fuel gauge, water temp, etc., but the colors are consistent on both harnesses.

 Ground - B/W  black/white
 Keyed power - GR gray
 Tach - B/Y black/yellow
Turns - Black for LH and Light Green for RH
 Neutral - LB blue/black
 Hi-beam - Y yellow
 Oil Pressure - G/Y green/yellow
 Fused Power - OG orange/green

I won't be using the side stand switch or clutch switch (this is all going in a GS550 frame). If I just use a jumper for those two switches, will the turn signal/side stand relay in the 750 harness still supply the correct power and ground to make the neutral light work?

I studied the 750 diagram yesterday and all of the colors I need match up. I ordered a Bandit 400 harness to rob the plug from.

On the Bandit 400 diagram, OG is switched power from 10A fuse (4 Signal) for turn signal flasher, back brake switch, horn, front brake switch, side light switch and pilot lights. Neutral light is supplied via switched live from OG, LB is earth via the side stand diode to the neutral switch.

The 750 doesn't use a diode (or, if it does it's inside the turn signal/side stand relay....lower right in the 750 diagram). Sooo....if I just use a jumper to bypass the side stand switch and the clutch switch, will that relay still supply power to make the neutral light work?

Edit: I ordered a genuine Suzuki clutch safety switch this morning. The wiring and mount is there for it, so I figured $12.86 shipped is like hitting the easy button AND adds a little bit of a safety factor.

I'll still have to bypass the side stand switch. The 550 frame has no provisions for mounting one.

Scott - did you ever get the SR500 going ?
I was following your thread (not that I could add to anything).

[Scott S]

 Yes and No. Got spark, got it running a few times,even rode it around the neighborhood.  But carb tuning was off and starting it was a royal PITA.  I re-injured my ankle....pretty badly. Old work injury.  I'm actually wearing a brace as I type this.
 I sold the SR500. No more kick only bikes over ~150cc!!
