my question is ,how to install a non oem tach on my sentra e(it did not come with a factory one,so i bought a new autozone separate unit,made by autometer.)?
What confuses me the most is where do i hook up the wires? my previous cars were all 1973 and older muscle cars and trucks,and they only had one fuse box,and i always hooked up the accesories(stereo,etc) to that,but this car HAS TWO FUSE BOXES:ONE IN INTERIOR,NEXT TO THE INSTRUMENT PANEL,OTHER UNDER THE HOOD.
I am confused and neither this site or chiltons lists any info on this,and the directions given by autometer are shitty.
SO PLEASE HELP ME OUT GUYS AND GALS

thanks in advance

hook it up to the fuse box in the car,
run a wire to the green wire in the distributor for rpm to show up,

It's pretty much what you saw. A hack saw, a drill and a file are all you need to make it. The only change I would make is to bend the eye-bolts so that they come through the vent straight instead of at an angle.

I tried my best to describe it with that hand-drawn pic, but I don't have any more detail than that.

Oh shoot. I just spilled my breakfast on my keyboard........

hey man

THe distributor signal is fine but some tacho's need the rev signal from the ecu to work correctly and accurately. I used the neg side on my coil it worked fine but the problem was the rev limit was 9700rpm according to the tacho (the cool PIVOT one) i knew that it wasn't right my sr20 wasn't no damn honda revving that high so i took it to my boys shop and found out that the 9600 was acutally 7800.
so i decided to klink the signal wire to the msd where the tach adp. outlet was. wsame 9600 redline
so i just hooked it to the ecu and it read jsut fine

Absolutely not, that was not overlooked because the MSD HAS A TACH ADAPTER ON THE UNIT ITSELF. and thats where i got the tach signal from, the MSD box itself. I know what msd stands for and if that was the case the revs would be reading 6 times what it was suppose to be. hey man i was just trying to help and let you know from my experience :rolleyes:
