Ive been searching the web for some info on installing an aftermarket Tachometer on a '96 Civic, or a '96 Integra with a B18 in it. I can't find what Im looking for. We installed the interior lights all correctly. The tach comes on, the lights come on correctly, but we cannot find the proper location for the signal wire. We tried what we think was the negative terminal on the starter, nothing. The only time we get it to to work is putting it in a spark plug wire, but it seems to be sucking power from the cylinder. I searched here and all I came up with was the blue wire in the two wire harness coming off the distributor. I tried a few blue ones coming off of it but nothing worked. Any help would be greatly appreciated!

Use hand signals

^^he is talking about getting a signal for his tach to read RPM's not getting his turning signals to work...Bump for you.

Haha, yea thanks.

Im sure its something w/the distributor. Ive seen some use MSD boxes for their tach.

Napy

MSD Boxes?

i think theres a blue wire connected to nothing on the driver side, its the signal wire you connect your autostart to if you have autostart wit your alarm

Im pretty sure you have to tap into the VSS Vehicle Speed Sensor find an ecu pinout should be able to find it..

There is a 2 wire conector next to the distributor. The black w/ yellow is the power for the distributor and the blue is the rpm signal wire. Hook the green wire from your tack to that blue wire. There is also a 2 wire conector with the same 2 wires on the drivers side srut tower.

Sweet, we will give it a try today.

So we are still not having any luck. Here is what we tried so far:

We tried this blue wire that comes out of the distributor, but no luck, and the wire does not come out of the second harness as shown in the second photo:





This is the harness on the drivers side strut tower, but there is no blue wire at this point, it is the yellow and black, and a black and white:

I don't if this help but in your third pic of the driver side do u see the single blue wire going to the white connector. well in the civic that is the tech/rpm wire.

Napy

Yes, and we tried it with no luck.

that sigle blue wire going to nothing in the third pic is the one you should be using. if it doesnt work your tach is no good. you cold also get it behind the cluster. all you would need to do is check continuity with that wire and the solid blue wires behind the cluster till it beeped. if you went hooking the tach up to all sorts of power you could have fried it, thats why there are no returns on electric parts.

Napy

Are there any fuses associated with this blue wire that I can check? The Tach is working. I comes on properly and does the cyl. check fine.

Napy

So, we still haven't had any luck. My buddy told me last night though, his speedometer and odometer do not work at all either. Could all of these be related to a faulty wiring job? All the fuses seem to check out.
