i installed a shift light that i had in my civic its a 93 ex i used an rpm activated switch to activate the light, i followed the directions, however i hooked the rpm wire to the back of the gauge cluster tot he tach and the tach stopped working, then when i disconnected the wire the tach worked again. do you know why? does anyone have any experience with the rpm activated switch taht could tell me exactly where i can take the rpm side off of?? any help is appreciated thanks in advanced

 

bump for this question, im havin the same problem.

 

not enough power to power both tach and aftermarket tach!!

tap in at the dizzy....

 

i dont think thats it, i think it has something to do with the negative switch on the rpm thing. cause ive ran several shift light from the same place.

cut line?

 

nope

 

anyone

 

Maybe the shift light bypasses the RPM signal to your cluster in order to fully have a 100% signal to the light?

 

but the light doesnt light up either


this is how i have it hooked up

RPM SWITCH
red-12v switched
black-ground
yello-to ground wire on light
white-tach wire

LIGHT
red-12v switched
black-yellow wire on rpm box

 

just tap it into the dizzy...thats where most tachs and **** are wired up to

 

im getting signal from the tach, i doubt tapping into the same wire 3feet away is gonn amake a diff. shoudl i be using a relay?

 

your getting a signal? which means when you rev it the light goes off right? but the cluster isn't moving?

 

no the light doesnt come on either, the rpms arent activating the internal relay

pick wat works for you and follow the directions

 

im pretty sure i need to use a relay

 

well if thats wat it says...GL

 

it doesnt really have instructions for what im doin. im not hookin it to a shift light im just using a auot light bulb.
