I've decided im tired of not having a tach, and plan to put a cheapo sunpro super tach 2 in my 1992 ka24e 2wd hardbody.

I was just wondering if anyone could tell me the red-line of my engine and maybe what i need to connect the tach wires to? thanksssss

One option may be to PM the person in the quote below:

If anyone ever needs any wiring diagrams of any sort, I have EVERY SINGLE ONE. I have S13A, S13B, and every year of S14 (they changed every year). I even have SR20DET.
The other option could be to try these links:
1) http://forums.********.com/zerothread/199928
2) KA24E Wiring Diagram - Google Image Search
3) closest I could find was a 1996 model
Download PDF Nissan Truck D21 Series 1996 Service Manual | PDFTown.com

Good luck :)

Come on guys, somebody HAS to know something. The paper that came with the tach says you hook up the green wire to the white wire on the wiring harness. Splice it in.

Now, i don't want to do this until I find out if someone has done this before or not. This is to send a rev signal to the tach.

And what is the redline of my ka24e?

thanks. I figured that part out earlier. What i'm trying to figure out is there seems to be a huge number of white wires in the harness. More than three. Some of them are striped I've noticed, but i just want to make sure i don't kill the tach or the computer by splicing the tach into the harness. All the paper says is, "under the seat, ecu harness, white wire." THe kit came with those red splicer connectors.

alright guys well thanks. I don't exactly feel like drilling, but i probably will end up doing it anyways.

just out of curiousity, is it a safe thing to do. do any of you guys know if the white wire in the harness is the tach signal? i mean, i already have the seats out and the carpet up and the wiring harness unbolted from the computer.

did it seem to be accurate though? Ive decided to scrap the ecu idea, seeing as i cant find the wire. they all have some kind of other color on them. negative side of the coil, ok got it. there is a plug.... ill figure it out.
