Tripper Delete and Tachometer Install

[Ike208]

Hey, @Ike208 - let me know if there are / were errors with the wiring diagram, with what you found, or are things worth annotating on the PDF, and I can annotate and update the PDF and re-upload it. I have zero... zero issues doing that. Zeeeeeeero. I'll happily annotate and provide citation for it, so that if the document then wanders, folks would know why the citations are there and that it's not a RE comment (and would include a date, for an as-of).

I'll holler if I see anything. The only reason I needed the diagram for this project was looking at the ignition coil and which wire I needed to tap for the signal. That was correct on the diagram, the correct wire from the ECU was a two-tone wire like Stig mentions above, don't recall if it was red/white or blue/white, but what the diagram mentioned synced with my bike. The other wire was orange, so it was a clear difference.

The Orange wire is a switched +12V feed.

Thanks for all the directions. I purchased the same Daytona tach for my Scram 411 and did the install wrapping the spark plug wire 6 times per the directions and setting the 1 pulse per 2 rotations correctly. It picks up the idle RPM well, showing just under 1500 rpm. As soon as I accelerate the signal rises and gets a little noisy but its showing 8000-9000 rpm when I am at about 3/4 throttle under acceleration nowhere near the rev limiter. Obviously, that is not correct. I am going to try the direct wire method you mentioned. You just spliced to the signal wire heading to the coil, correct? Thanks!

The velona 48 I used gets the signal from the coil +ve. Cable splicers can be bought on Ebay.

Rather than stripping/cutting/tapping wires, I found the two-part Sumitomo connector at the coil that serves the two-tone ECU wire (the one to tap) and the orange switched wire. I disconnected the connector, then basically folded the tach's signal wire around the male part of the connector, then plugged it back in. If I recall correctly I had to use a longer wire than what was supplied with the tach and all I had here in black insulation (didn't want colors making the wire obvious) was heavier gauge than the rest of the tach's wiring. SO, when I tried to clip the wire inside the connector using the whole wire was too much, so I ended up peeling back about half the strands and clipping it in that way.

I started a thread about adding a tacho to a classic 350 under Classics. There are links in that thread to various suppliers of Sumitomo MT connectors.

Great suggestion!

Splice into the coil connector worked perfect. I got that and the FuelX hooked up tonight and it worked! RPMs nice and smooth and where I would expect them to be. Thanks for the advice.

I may end up going this route. The tripper for me, is useless. I don't travel far. I've used it for being a clock.......and now it runs 15 minutes fast and is gaining, so it's not even a decent clock.

For what it's worth 2LZ, you need to synch your phone with the Tripper via the RE app, it should read accurate time then at least untill you install the rev counter

Did it when I bought the bike. I'll check it again, tho. It may have "unsynched". I had a glitch last week. I made the mistake of firing the bike, then chatting with someone for a moment before taking off, and I forgot to flip up the kickstand. It lurched and quit......and reset my little clock on the big gauge by itself. Weird. No issues since. Lesson learned. Don't take off with the kickstand down.

With the dashboard now loose, you can easily access the two bolts that hold the Tripper to the dashboard. With the bolts removed, follow the wiring from the Tripper to the 3-pin Sumitomo connector, pop it loose, and the Tripper should slide right out for you.

Huzzah! No more Tripper! Really, this is a G.I. Joe "half the battle" moment as I'm just glad to be done with it. The hole left over is a bit unsightly, but I have no doubt that even if I wasn't installing a tachometer I'd find SOMETHING to put over it: funny sticker, little mascot, whatever.

Now, with it gone, it's time to test-fit the tachometer.

Hello, I have a scram that came without the tripper and I am wanting to install it, I have the original plastics with holes, some want them with holes, others without them, heh, what I can't get is the cable that connects the tripper, is that Sumimoto connector? Does anyone know the part number or where it is sold? Thank you !

They're (if I'm using the term correctly) a three-way Sumitomo connector. I got mine off Amazon, here's the link. They ship from China, apparently in a rowboat because they took FOREVER to arrive but when they did they were just what I needed.

Very helpfull, but the major problem is the other conector, the 2x3 pin attached to the tripper, someone know the name of this connector, or maybe used in another bike , car? thanks!

AHA, now I get the problem, your connector is probably the "six pin connector" that @Stig57 had to deal with when doing a similar tach install on his Classic. Boogie on over to the Classic forum to check out his writeup, or check with him to see if he has any leads on where to get the connector and/or how he tapped into his. Here are a couple pics of what my Tripper looked like when I pulled it, no 2x3 connector to be found, just the 3-pin Sumitomo.
