IF you have the installation instructions for the tach, it prolly tells you where to attach the tach wire. If not, call the manu. of the tach or search for their website online.
on my tach, the green wire connects to the neg on the ign coil pack
If you don't have a distributor on your car, you will need to get a tach adapter for your car. So that you can get an rpm signal from your car to the tachometer.Hey dude, here's how to connect the green wire from your tachometer: Tach output is obtained from PCM (powertrain control module) which is a 104 wire connector, and is located behind the passenger side kick panel. Look for pin number 48, which is usually an orange wire with a white stripe.(4.6L is = 4 ppr)Your best bet is to check out the autometer's web site which provides most all the information you might need. If you can't find the info email autometer tech support.Go to test connector inside the fusebox under the hood, it is a t-shaped plug. Tach is the terminal on the top left of the T. The wire under the terminal is white or white/red.
It should work ok if the wire for the tach under the hood is connected and I don't remember which one it is.
green signal wire goes to the negative side of coil, not the positive. On your tach you probably have a ground(black),power(red), signal(green) and illumination(yellow?) wires. The signal wire splices into the positive side of the coil. The rest of the wires are pretty self explanatory. Make sure you have a solid ground and power. The illumination wire can be hooked into the headlight switch so it goes on with your lights. Tim The statement above is true for hooking up a tach. I just installed one in my 87 gmc s15. the trucks are set up from the factory to come with one, so you will find a wire located in the wiring harness that has a hookup for your tach. This is so you dont have to mess with the distributer set up. This may save you some time.
the red one
pin 48 on the pcm connecter is tach signal connect to your green wire from tach
run it to the blue wire on your distributor. That's the tach lead.
hook your green wire from the tach to the white wire from the coil PAC it should be a white and a yellow wire coming from the coil. the tach should have a white wire that will be your light inside the tach a red wire for power and a black for ground.. good luck
Tachometer Filter Tach Wire Plug Connector ON A 1979 TRANS AM
you can install any kind of tach you want to in your car..if you do not have a stock tach then look in your manual for the rmp sensor wire..should be blue or green coming off the distributor...just splice into it...if you have a stock tach you can just splice into the stock tach wires by taking off the dash
If the tach wire shorted or melted.
On the 88 jeep the trigger wire at the tach is blue.
hard to find the tach signal wire due to the fact that the ignition coils are built into the distributor (old cars always easy to work on) to get the right wire l have posted a page on how to install a tach to your Mitsubishi. go to www.sureyya.biz and click on Mitsubishi tacho install. Dont forget to give feedback on how useful the info was.
a tachometer, wire and wire terminals
In order to install a tachometer on your 1987 Monte Carlo SS, you must first find the tachometer wire by using an automotive diagnostic tool. Mount the tachometer on the dashboard. Connect green, red, black, and white wires to the distributor, ignition power, cigarette lighter, and headlights, respectively. Turn on the engine to test if the tachometer works.
its the blue wire, alot of ppl run it off the distributor, but why, when these cars came with a tach in the Si trim, just splice into the blue wire on the gauge cluster harness
On the distributor cap where the wiring hooks up is a terminal that says tach. Install the red wire to it and the black or ground wire to a suitable ground. Sometimes the tach has a green wire that connects to the white one coming from the ignition coil plug side that has 2 wires
