PB, I'm working on getting a set of used 2017 EX gauges operational for Deano, waiting for a used eBay connector plug to test the meter assembly

Wow, that is a lot of Honda, just to get that plug, but I guess it is the only way to be sure it's the right one.
I had ordered something similar for this RS from Aliexpress, but the slide and grooves of the body did not match up.
I will be out in the garage to photo what I have here as wiring & connections for the gauges (damaged off RS)
Many thanks, Deano

Hello all,
I am getting desperate now.
I need to find a set of instruments for a CB1100RS as mine were smashed in an accident. I tried replacing with CB400 vtec Superfour's, but out done at the end by the white comms wire, from the ECU. As I can't get help on how to overcome that issue, now looking to buy a set of clocks (instrument assembly) complete.
Can anyone help, any where please, anyone breaking a CB1100RS?
Many thanks, Dean

Are you not able to get replacement parts from Honda?
RE: m-txd/rxd wire (white) ecu to instruments communication - pekingduck - 01-13-2026
Only the outer case coverings are available. The speedometer, tachometer, digital panel, main circuitboard, harness, and the big inner white casing everything bolts to are not available.

Bummer. I thought Honda kept spares for 10 years?

I already sent cluster request to my Honda / Canada friend and awaiting his response.

Yes, for around $1,500, which is crazy money.
Someone out there must be able to help without me needing to spend that. With the CB400 Vtec Superfour assembly on there, I had figured the speed, revs, fuel etc etc....just came down to that White comms wire, rendering all my hours of work useless, which sucks.

That's a lot of dough.

Can you provide the correct P/N for the cluster you need , is it 37100-MGC-CC2 ?G
You have a 2017 Honda CB1100RS?
Send me your VIN by pm or email.
In your case, I operate on an international market, so is easier for me to provide the correct part number, some sites request VIN to avoid errors!
One answer so far from a dealer, Canadian site is listed:
Gauge Cluster, 37100-MGC-CC2, C$1253 +13% tax + S&H, back order March 11-24
Expecting more info from Europe...
