I was fortunate to acquire a brand new Mini-tach that mounts on the Handlebar cover of my 03-RKC. Part # 67201-04A. It has three wires, Black, Pink and Orange/white. I know the pink one is signal and there is a pink wire comeing from under the nacelle that I know is the signal for the tach. The black I have to assume is ground and the orange/white is power. My question is, the instructions want me to plug the pink wire into the speedo however those instructions are for a 20O4 and up. Again I know where the signal (pink) wire is so I can tap into it easily, however the orange/white wire, they are suggesting I plug into the back of the fuse block marked "P&G IGN". This of course is for a 2004 not an 2003 and is a 2 amp fuse. My question is given I may not have that fuse block can I connect the orange/white wire to a power source and install a 2 amp inline fuse for it. I don't want to mickey mouse this but I don't think I have that in the fuse panel and my service manual picture of the fuse block looks nothing like the instruction block. Again difference from 03 to 04 I suspect.

And please I already know that I don't need a tach, but I got this one cheap and new and unused so its going on the bike.

Thanks

Problem solved. I found the pink tach wire under that nacelle and a capped orange/white stripe wire there as well as a open ground wire. Hooked all three up and it works. No routing wires back to the fuse panel because that hot wire is fused anyway through the block I'm guess. everything tucks behind the head light.

Glad you got it figured out but a word of caution. If it is an external as I suspect make very sure it is kept as watertight as possible. I have an aftermarket tach on my Road King and after numerous times getting wet it finally took a dirt nap. An Indy did this for me on a makeover and will get it taken care of but our situations are different so heads up just in case.

 

This tach is an original HD mini tach. Comes rubber seal and is a solid sealed unit. I tried an after market one a while back that went into the dash. Wouldn't stay working even when I replaced it. Drag Specialties combo. I got rid of it and installed a 2-5/8 mini tach right from HD. Was discontinued but my dealer had one in stock and gave me 20% off so I bought it.

All done.

Well done...

 

So I went for a ride today, wasn't too cold up here in Ontario. With this new tach, I noticed the speed on the speedo and what read on the tach. For 80 km/h (50 mph) the tach read 2000 rpms. For 100 km/h (62 mph), 2500 rpms and for 120 km/h (74.5 mph) it read 3100 rpms. I don't know if that is good, bad, exact or way off. Can anyone shed some light on those numbers.

I like your better than mine 'cause of the center location.

 

This is about right for a 5 spd, transmission.
Best I can remember for my 2000 Ultra it ran just under 3000 RPM's at 70 MPH and near 3500 RPM's at 80 MPH.
Even tire wear can cause some variance in MPH vs RPM readings.
It always seemed to me that all of my bikes got better MPG's at 2800 RPM's.

 

Spot on. Although the tach is inop at the moment on my 01, this is about as close as can be expected, down to the 2,800 RPM/mileage. But most any HD I have had gets the best MPG at that range.
