Could someone please tell me which wire to splice my tachwire into in the harness? I thought it was the blue one but I spliced it and the tach still doesn't work.....hella frustrated!!!!!!!btw, it's a 4door too. thx

 

The blue wire coming out of the dizzy is the tach wire. Dark blue, w/ one other wire next to it going in to the plug.

if you tag the blue wire outside the dizzy, you get the signal before the Ignitor and it doesn't work with some aftermarket tachs. run your wire straight to the coil itself inside the dizzy.

 

ummm...sorry I'm not that good with wiring and stuff and could use a litttle more explanantion please. I only saw one blue wire and I spliced into it but it doesnt work..it comes out of 2 dizzys right? Does it matter which dizzy I splice into? Where is the coil at inside the dizzy???thx

 

by dizzy i mean distributor.

you'll have to pull the distributor cap off and look inside



the coil is #15 in this pic, there are 2 wires going to it and where the wires connect the coil has a (+) and a (-) etched on it.
You need to figure a way to get your tach wire into the distributor without causing any holes that water could leak in to and attach it to the (-) side.


Edit: or beter yet, get an Si gauge cluster and plug it right in to your dash without running any wires under your hood:

you don't need to run it all the way to the dist... the wire is on the driver side firewall but sorry i can't remember which one

 

I also need to know this info.. I've got an autometer shift light and I need to put it in my 91 DX with a B16.

Anyone?

 

pin location B15 at the ECU

 

YES!!!!!!!!!!!Thanx a lot guys...got it working and I tapped into a fuse so that the tach turns on after I turn on the ignition........Now I just need to know how to make it so the tach only lights up when my headlights are on???????????

 

you can pull the illumination lead from the cigarette lighter or the radio illumination or even the HVAC controls.

also, i found out that the tach wire is in a harness that plugs into the fuse box. its the dark blue wire with 2 silver stripes on it (for me and my 89 civic). i'll try to get the pin number later when i have access to my manual.

thanx i got the tach workin...i just spliced into the blue one coming out the distributor and that did the trick...so now i just need to splice into one of the wires going into either hvac, radio, or cigarette??Is it a certain color or is there just one wire?????

 

Edit: or beter yet, get an Si gauge cluster and plug it right in to your dash without running any wires under your hood: i believe this will give a VSS error code.

 

i was saying in my post that illumination wires run to the radio, cigarette ligther and HVAC controls. you can grab the illum. from anyone of those.

for me i just cut the illum. wire going to the ashtray and ran it to my tach. i don't have much interior, so i didn't need the illumination going to the ashtray.

 

the wire you need to tap into to make the light work is the RED/BLACK.
it's everywhere behind the dash so shouldn't be hard finding it.

 

to find the ilumination wire just go to the fuse box you will see 4 male spade terminals i beleive 2nd from left is parking lights, only down fall of this is that it will iluminate at full brightness at lss times the lights are on, you could get a resistor or even a varible resistor at radio shack and put that in the wire and set it to a good brightness an hide it under the dash or put it some where you could adjust like in a blanke pannel.

 

YYYYYEEESSSSSSSS !!!!I'm hella happy, the tach is workin perfectly and i got all the wires in place even illumination......thx for the help guys
