Hey everyone, i just bought an aftermarket tachometer for my 92 mazda protege turbo project car. anyways, that's not running right now, so i wanted to test out the tach in my tc. does anyone know how to wire it up?? thanks

What brand tach is it? Most tach's require switched 12 volts, ground, illumination and the tach wire from the car.

it's a pivot stepping gauge.

it has 4 wires, ground, illumination, ignition, and tach signal. mainly i'm just looking for where to tap in for the tach signal.

Tach- Black wire data link conn. under dash, pin 9 or the tach wire is also found at the ECM behind the glove box, top plug, pin 5.

cool, i already took that connector out and looked at it and found pin 9. i was wondering what the best way to tap into that would be.

Peel back the outer sheiding of the factory wire and rap your wire around it and tape it up with electrical tape (if it was going to stay in the car i would recomend soldering it to the other wire).

mandangalo

cool, thanks man.

No prob and good luck with your project.....

hmm, so i got everything hooked up, but the tach signal wire isn't giving any signal....either that or i got the wrong wire. does anyone have a pic of which wire on which harness is the tach signal?

Does anybody know where to tap in for a Light... Just installed a Boost Gauge, but don't know where to tap in for the light?

soros151

any 12V?

Ya, but I want it to come on with my Dash lights...not always be on.

Then tap the Accesorie fuse under the dash using a switch. There u go, as simple as that. :D

any illumination wire.. they're all over the car..

Just gunna use a Volt Meter Gauge to find a proper wire.

All (+) wires carry 12v (11v-13v).... it's the same....
