A simple factory tach ?

Surely it's not this easy......Converting to a factory tach numberoneson just bought. On the back it shows: 12V and TACH" above the spade terminals. Is that all that's needed? Just a power wire and a wire run to tach side of the HEI unit?

thanks in advance,
Steve

Is it a complete tach conversion kit,a replacement for a truck that already has a tach,or just a tach?If just a tach,you would need a lens,backing plate and circut board.

Mike,
It's even better. He found a used complete dash for $100. AND it's in good shape. Now as long as I can figure out the wiring and it works, we'll be in good shape.

Numberoneson is a lot older than the avatar looks, but it's the right idea for the last 2 years workin on his truck.
