Hey folks, I need some tech help here with my 97' Formula (A4). I want to install this Autometer tach in my car. But... I have never installed a tach before. I dont have the stock coil setup (running delteq unit now), so I dont know if that changes anything. I'm pretty good when it comes to wiring though.

How hard is this too install? What wires do I need to tap into?

Thanks in advance,
Mike

 

why not just install a shift light?

 

Because its an auto, it upshifts on its own. A shiftlight is like a warning to tell you to shift. Well I dont have a manaul valvebody. So it wouldnt work for me.

unbolt the ecu and look for white wire #13 on the RED connector, then just get a wire tap and tap right into it. for ower supply i got mine from the fuse panel, light i connected to the power for the parking and headlights, then just ground it under the dash.

 

TY, looks like the only hard part is routing the wires. I'll prob just route it through the factory spot.

I was just wondering, does that wire run under the dash? If so, I'll just tap it off there, instead of at the pcm.

i think it does because i have heard of people tapping in under the dash. i just routed mine behind the weather stripping and in the door jam works fine and you cant see it.

 

Awsome,

Maybe I'll do some kind of a install guide for people who have never done this before.
