Bonneville America Forums Forums Technical Forums General Tech Tacho

Hi, Has anyone fitted a tacho head to the newer models with the black face? I bought a tacho conversion kit from the local stealership. Comes with a tacho head and nothing else. When I tried to fit found the following. Its a six pin set up with 3 on top and 3 offset below. When you try to insert the male plug from the main harness there is nothing to hold the plug in the female on the back of the tacho. Its rubber encased with a slightly raised edge (the male unit) On looking closer the depth that it engages is not sufficient to engage the pins in the female unit. There is a elevated plastic guide on the housing that prevents it from going in any further into the tacho housing plug. The female plug on tacho housing has two lugs on the exterior that look very much like engagement points for a switch clip. I phoned the stealership who inform me it just plugs straight in. Maybe I am losing the plot in my old age but I had the young mechanic next door look at it and he came to the same conclusion as I did "No way Hose" Any ideas etc?

I put the black face tachometer on my 13 America last year and ran into the same problem. Backed off and drank a cold beverage then looked again. If I remember correctly, I had to remove a nut on the back of the tachometer before I was able to plug it in. Had to look close to figure this out. It has been a year since I put it on but it was simple plug and play once I figured it out.

ok. I just looked in my tool box and found the culprit. On one of the pig tails,I believe it was the bike side,is a black plug about 1 1/2 inches long. Remove this and it will plug right in.

Thanks- problem solved- beats me why the put the dummy plug in. I owe you a beer
