yes what I am saying is that the blue/white or blue/black wire at position 41(IIRC?) from ECU would not give a signal to an SE-R gauge cluster I tried to rig up.

I know that wire would not power teh Sunpro tach; for that one I am using the green/yellow(?) IIRC from the coil. But you can;t use that wire to power the gauge cluster tach; it shorts the car and it wont start.

Coo"?

What exactly does a tach do for your car?

It is an information gauge. It informs you on how many rpms your engine is going. And if you dont know a rpm is a revolution per minute. So when your engine makes a complete stroke that is a revolution. Knowing your rpms can help in shift times and just being able to know how fast your engine is going.

i used the wires listed on this guide, and everything hooked up well to my $30 sunpro tach II gauge. only 1 problem, the light on the gauge does NOT dim, is on full brightness whenever i turn the lights on (not a real issue tho)

the instructions from the sunpro tach say to use the blue/black wire.. 2 did nothing and the 3rd (that i found) gives some reading, but no where near the correct reading.

the Light blue/white wire did the trick Thanks again.

BTW, its a 94 B13 XE 2 Door with only minor engine mods

I too installed a Sunpro II in my '94 XE, following the write up and it works perfectly.
Thanks.

ok so i hooked it up to the blue black wire like the guide said, and i'm getting no reading...will it hurt if i try the blue/white wire like you?
this is coming from the ECu on the right side(passenger with that plastic shield gone(one metal screw and one plastic)

thanks
