So has with a truck or car,, you have the 12 volt coil which is needed for a tack.. Now you also need a ignition power on lead.. So when you turn on the key the tack powers up.. So here this tack has 4 wires. 2 for + - lead on tack,, the other to a power AC on and negative to battery... Hope I did my best to explain… see more So has with a truck or car,, you have the 12 volt coil which is needed for a tack.. Now you also need a ignition power on lead..

Red to anything that has power. Black ground. I put green to ignition module I think

Yes it uses the coil as source of reference.

Nice little tach for the money. I felt that the instructions were lacking quite a bit, but I was able to figure it out. There are two long red and black wires - these provide power. The red should be hooked to a 'key hot' wire. There are two shorter red and black wires - these are for the backlight. The red wire here should be hooked to a wire that gets hot when the parking lights are turned on. Finally the long green wire needs to be hooked to the signal for the distributor. For my Chevy HEI ignition, this was a wire directly to the distributor cap. The response of the needle is nice and smooth, not choppy or jittery. The backlight is a very bright blue. The bezel is just ok, the holes in the back of it for the wires to pass through are on the wrong side for how I have it mounted (base down to the top of my dash). This seems wierd to me, the wires come out of the top of the tach itself when oriented upright. Didn't seem to cause any problems though.

The tach works good really good but the back light is way to bright even when hooked into the factory dimmer switch instalation was about 3 hours because instructions where limited and resorces online for my specific vehicle where limited when trying to find schematics for my factory dimmer switch and like many have stated the back light is wayyyyy to bright they would of been better off using a regular dash bulb for this thing think im just gonna cut the back light wires and leave it as a none back lite tach over all for the price of this thing its definitly worth it

Gauge worked on the first try, ran the green wire to tach output off the coil on a 350 TBI. It won't read any rpm until the engine is actually running, not sure if that's my truck or the gauge.. But it seems to react reasonably quick and read accurately. The gauge pod is very cheap though and mine was missing the back side of the nut, so I had to drill it out and make a new nut/bolt... But still a cheap way to add a tach to a truck. Update, now that i wired the LED backlight, it is WAY too bright for nightime use, I wish there was a way to dim the backlight some, I wired mine to a switch so I can turn it on and off. Also you can combine the two black negative leads (one for the tach and one for the LED) at the same spot, works fine and makes wiring a bit easier

Installed, started engine and was happy to see it setting at about 900 RPM.... Drive to work and will only run up to 2000 RPM. I know I exceeded 2000 RPM but that was as far as the TACH would go.... Selector set correctly (4 cyl engine). I really don't want to remove the TACH because I soldered all the wires.... any suggestions before I have to cut all the soldered wires??
