got a tach for cheap on ebay,,no instructions though,where does the tach wire go,,,,? coil?? or is there a wire somewhere I neeed to connect to,,,,1998 dyna wide glide (carburated)...thanks ,headpan
-
Depending on the bike there is a wire under the dash that is for a tach hookup (my 00 softail had one). If not the coil will work also. I have a manual for a 98-99 Softail (I know you said Dyna) that I could look in the wiring diagrams for a tach lead.

I thought the coil would work, thanks bro :2vrolijk_21:

On my '98 Fatboy, it went to the coil (HD tach that developed issues).

what kind of tach Gecko??,,I had one on my 86 softail for 18 years and worked flawlessly till i sold the bike,,the one I got on ebay was defective ,,the needle bounced and was out of tolerece by 200 rpm..sending it back 2day,,,I liked the 2-5/8 one ,,but if there is issues with them,i will get the older /bigger one like on my old softail..I knew the tach went to the coil,,but was told about a hidden wire under under the dash(that I did not have)....

Shortly after warranty expiration - naturally - the inside of the front bezel developed what looked like moisture condensation. Only it wasn't. It dried to a cracked coating that clung to the face. The needle froze at about the 1K point, and was not very responsive. Those things are very difficult to break into by the way, all I ended up with was bloody fingers. With nothing to lose I stuck the tube from a can of WD40 in the back and sprayed a little in. That helped for awhile, but it hasn't worked right for the past nine eight years. Doesn't matter that much though, you just wait until your feet start to vibrate off the floorboards and it's time to shift. Redline is when both mirrors suddenly droop.

HP,
Did you get your tach installed? If not, I've got 97 WG that I put a moco tach on. I'm pretty sure it went to a wire under the console. I can check this evening for the directions. I should have them. Just let me know.

Not sure how many wires you have, but basic tach has three, installation can usually be made to the coil, but ECU controlled motors usually have a pin on the ECU connector for a tach.
Red - power, connect to a Switched, fused power source.
Black - Ground
Grey? - Signal lead, negative side of coil.
There might be additional wires for a light, you may need to take off the back.

Here's what the moco instructions tell us on 98 and earlier: Your hot lead (red on the moco tach) goes to the speedometer power post inside console; ground (black on moco tach) goes to the connector on the back of the speedometer; and the signal (yellow on moco tach) goes to the coil primary which has a blue or pink wire attached to it. On some tach kits, you're supposed to connect the signal wire to the ignition harness connector (should be connector #8 in the service manuals, under the right side cover), position #3. There needs to be a splice made there. I think I'd try just removing the pink wire from the connector and trying things to see how they worked. For some reason, the FLHR's don't need that pink wire, yet everything else does????? I'm not sure why that is, but that's what the directions state. Hope this helps. I like my tach on mine, not that I use it much, but think it looks good there.
