If your bike is not EFI- I’d be surprised if it works.
I think I’d be surprised if it worked in any case.
I do VAGUELY recall somebody offered wiring ‘kits’ to allow instrumentation to ‘make fit’ on different bikes- but that was years ago and it’s only a memory.
I changed the speedo on my ‘08 Deluxe to a combination speedo/tacho unit and it was a very specific fit.
I can’t even find that part number( 69776-06) in my ‘08 “P. and A” catalogue. Actually, I can’t find it anywhere.But the”06” on the end suggests it’s for an 06 bike.-when the part came out.
Can you take the tach and your bike to a Dealer ( and I HATE saying that) and see if they can offer you some assistance.
If you’ve purchased a combo unit- and you can get it to fit- you’ll need to see a Dealer anyway to have the mileage reinstated.
