hey guys, i recently bought a sunpro tachometer teh other day becuz i got tired of driving by ear and looking at the mph to shift gears. its the the stock 91 hatchback motor, the problem im' having is teh green wire.....i did a search and installed it to what i found on the search....one search said wire it to teh dizzy and another said to wire it to a blue wire near the driver side tower. i did both but the meter on teh tach doesn't move. could it be my ground maybe? i have the ground wire wired to the battery wire to neg. i can't find anything other solution. any help with this? if you can supply a pic of where i need to wire it that'd be very helpful. thanks


(i posted in the EG+ Civic / Del Sol was told to see if i can get an answer here.)

the way i have it wired now is
red- into my cdplayer's positive ground wire
white-into the fuse box under the dash where the headlight fuse is at
green- just hanging around
black-wired into my dashboard light

i prolly have it wired wrong

anyhelp please???

Lol...

Red is battery power, hook it up to ignition 12v power source
Black is ground
White goes to dash lights dimmer
Green goes to RPM sensor wire, its on your ECU.

 

um might get flamed for this but i dont care, i'm learning still
where is the ecu...???
and um what does one look like

Its okay n00b

Your ECU is on the passenger side under the carpet, looks like a metal box under the dash.
Green wire on ECU is RPM sensor wire.

 

ok i think i found the ecu, its alil box with wires from it right...???
which wire do i wire it to? the blue one?

i rewired everythign
Red -neg wire from battery.... (wrong huh) not sure where to wire it
Black is ground (onto the frame of teh dashboard, prolly wrong agian huh)
White goes to dash lights dimmer (i got it )
Green goes to RPM sensor wire, its on your ECU. (the blue wire?under passenger side?)

Red - any 12v power source that gets power when you turn key.
Black - Any ground
White - Dimmer
Green - RPM Sensor wire (see ecu pinout)

 

STOP STOP STOP!!!!!!! HANG ON A SECOND!!!! ok the green wire does not need to goto the ECU. if u go into the engine bay, look close to ur distributor and there is a blue wire which is the ground. take the green and connect it in there and presto!!! ur tach will come to life. If u need a picture send me ur email and i'll hook u up with a picture.

think u can post a pic of the ecu just so i know if what i'm looking at is what it is


and teh black wire, its grounded where i put it right? the frame of the dash is ok?.....

Yes, that'll work.

It makes the install cleaner, but whatever works...

 

youd be better off playing it by ear than using the sunpro tach. those things are terribly inaccurate.

 

hmm.....my blinkers dont work now

 

I recommend that you check all of your fuses. Ok if you are having a hard time wiring this tach please stay away from the ecu there are alot of important wires there. If you miss count a Pin you could wire it wrong and mess up the ecu. I would try the wire in the dash behind your cluster or get rid of the sunpro tach and just get a Si Cluster or an automatic cluster they also have tachs.

As far as the wire in the dash im not sure what color it is but im sure someone will chime in. I belive its a blue wire, all the cars have it tach or no tach.Also remember to make good connections crimp/solder all connection to the main harness. It will make the difference later on.

 

i got teh tach to work now ^_^
now i'm on my way
gonna add a custom exhaust next and then an intake then just chill for a bit and save up for an engine


thanks for ya'lls help

i was looking at the convetations that you guys have had and i have a 91 civic HB and i can not find that blue wire out of the distibutor cap i was wondering if you have a pic of the one you set up so i can do mine. i have been tring for 4 days. thanks

 

There is a blue wire that comes out of the distributor. Its on the 2 wire connector. ITS NOT THAT HARD GUYS!!! C'mon, read and pay attention!

Common sense helps aswell....

 

damn, i figured it out , i did not realize that the other wires had to be pluged in i got it and it works fine thanks for the help guys

 

There is also the blue wire that goes into the gauge cluster on the left side.
