HMMWV Tachometer Installation

[CallMeColt]

Yeah, a little confused, heh... either the paperwork or photos of the 5 wires installed should be all I need. I'm not sure if the other (3) wires are hooked up to the fuel gauge wiring, but I'm hoping they are... the original alternator that was installed in this Humvee was complete garbage, so I'm guessing that's why the guy strung the (2) wires up to the alternator, but didn't actually connect them.

Right now, it has a new 60amp alternator installed... I've attached 2 photos of it below. I assume the metal cover you're talking about is the one with the yellow warning label on it?

Thanks for the help!

If I'm not mistaken, the kit is meant for a newer alternator. It may not work with the older 60amp one. My truck had a 240amp and it came off the regulator. Instructions show to hook it to the regulator. My thought was it was using the signal from the regulator & the older 60amp doesn't work that way?

Hi, has anyone installed the A2 tachometer (the one mounted on the window frame) in an A0/A1? If so, where did you route the cables? There doesn't seem to be a way to run them through the ventilation duct. I'd appreciate any pictures.

I just did. My kit came with a replacement for the duct or whatever you'd like to call it. Then, you cut a slight hole in the plastic vent that is behind the dash. Comes out very clean. Going to be installing another in an A2 here soon.
