I hooked up a second tach in my 89 crx one of the smaller super tachs
im pretty sure ive got power because the light for it goes on.
I connected the green wire which is supposedly the tach signal wire to to the blue cable coming of the dissy but still no signal.
Im not sure if that is the right spot ive heard it from a couple people
can someone please specify the best spot to put this wire.
 
Well I just looked at the install manual for that and all looks good. You do use the blue at the dizzy. That is where I got mine hooked up at. I would say use an autometer. I have it and its very reliable.
 
damn then i dont know whats wrong.
should it be hooked up right from the dissy or after the multiple wire thing.
 
Mine is hooked up right at the dizzy. You can get the signal from the ecu as well but im not sure what pin it is.
 
you actually ran a wire into the engine bay and spliced it into the wire off of the dizzy? dear lord. *facepalm* and an autozone sunpro tach no less. to each his own i guess.

there is no rpm signal input or ouput from your ecu. tap into the blue wire at your gauge cluster plug for the rpm signal.
 
i know what he means though, splicing with the dissy wire could alter spark transfer after a while of wear and tear
 
Not if it is done properly. Im a stickler for my wiring. Has to be done right and not look like anything was added just by looking.

Its ghetto to run a wire into the engine bay and hook it directly up to the distributor is what i'm getting at. the signal wire as i said comes into the car so why would you run a wire into the bay, its unnecessary. i personally dont understand why someone would need another tach anyway. if you have a stock one use it. if not, swap out your stock cluster for one that has a tach.

to yodaesu, the wire at the cluster plug is just blue.
 
yeah i understand its kind of pointless to hook it up to the dizzy but ive searched everywhere and the only thing i could find was people saying to either hook it up to the dissy or the ignition coil, which is the same wire.

but i will deffinatley switch it over to the gauge cluster.
 
*bump for update

it worked, thanks hatch.. i just pulled the wire back through covered the dissy wire and ran the tach wire through my dash to my gauge. looks nice works like a super tach!
 
i always liked those little sunpro tachs before i got my oem evo one. they work great, and are discreet.
 
yeah exactly, i put it in my center consoles right heater vent that broke off so it fills the gap haha.
And im boosting soon so im going to set up my gauge pod for boost and oil press.
and i might knock out the other heater vent for a water temp and or air/fuel gauge.
