Want to install my monster tacho, but am unsure of the wires, looked @ the Autometer site but they dont have it!

Problem is i bought the tacho off my bro in law and he had it prof. installed in his car, and doesnt have the wiring diagrams/codes.

So im after some help on the colours of the wires coming from the tacho!

Like what each colour represents!

theres four: red, white, green and brown

power, illumination, ground and revs?

but what colour does what!

Any help would b great!

Cheers

you dont need to wire it up to the coils, just tap into the rpm signal off the ecu. there are a few diagrams of the ecu layout on these forums; just do a search.

also, i think to correct steve i think green is for the rpm signal, and white is for the illumination. It is better to tap into your dashlight wire because it you can adjust the brightness of it with the switch.

Did you look through this page?

I can't imagine the tacho wiring to be different throughout their model range anyway :D

anyone have problems with the signal to the tacho? i've wired it up correctly but get no responce from the ECU?? when i turn on the power the needle goes to 0rpm but when the engine is running the rpm sits at 3000rpm and just stays there???

iv put tachos in many times, autometer being the easiest... best way to do it would be to take the cluster out and pull the plug out from behind the RPMs and then start the car and put the wires on the pins on the back of the plugs until you pick up the tacho signal, then splice or solder into wire behind the pin... thats what i did for my girlfriends lancer...

also if the signal doesnt read accurate check your earth wire, make sure its secure, a weak earth will make it inaccurate. better earth more accurate. test light will aid you

    • That's probably OK. That's a face to face compression joint between two surfaces with the clamping load provided by those bolts. So.... it's unlikely that the bolts will end up feeling that load in shear, unless the clamping surfaces are not large enough, bolts not got enough tension on them, etc etc to prevent the two faces from moving wrt each other. Which... I would hope the designers have considered, seeing as it's probably one of the most important things the upright has to do apart from resist collapsing in its own right. But yes, it would definitely be worth asking them what their safety factor on that part of the design was. I tend to think that the casting, being a casting, is not necessarily the strongest bit of material in the world. It's about an inch square, and when you think about the loads that are being put into it, you have to wonder what safety factor the Nissan boys (and every other OEM engineer who has designed all the millions of other uprights that look essentially the same) used to account for defective casting, aging, severe impacts on the wheel, etc etc. 
    • Those bolts would be orders of magnitude stronger that cast aluminium though.  And its mainly clamping force, not shear they are dealing with?
    • Except all that twisting force that is breaking a cast piece, appears to be going through 4 bolts in the picture Johnny posted of the BryPar one...
    • The smart approach is to use the gearbox loom from the manual car. Makes it a lot easier - just plugs into the switches on the box and plugs into the main loom up near the fusebox. Then you only need to deal with bypassing the inhibit switch. The other approach requires you to use the wiring diagram to identify those wires by colour and location, perhaps even indulging in a little multimeter action to trace them end to end to make sure, and then.... you will have the answers you need. The R34 wiring diagram is available on-line (no, I do not have a link to it myself - I would have to do a search if I wasn't able to go to the copy I have at home).
    • Hi, i’m converted my r34 4dr auto to manual but need help with gearbox wiring. There are bunch of wires no idea which one for speedo drive, neutral, reverse can anyone help me. IMG_6860.mov
