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

      Thanks for that, I'll check it all out. I can always do the brakes last anyway if its a problem.  The 16's are super cool, if they do fit I'll cruise around with them for a bit.

      Well, that's kinda the point. The calipers might interfere with the inside of the barrels 16" rims are only about 14" inside the barrels, which is ~350mm, and 334mm rotors only leave about 8mm outboard for the caliper before you get to 350, And.... that;s not gunna be enough. If the rims have a larger ID than that, you might sneak it in. I'd be putting a measuring stick inside the wheel and eyeballing the extra required for the caliper outboard of the rotor before committing to bolting it all on.

      OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup

      Well, apparently they do fit, however this wont be a problem if not because the car will be stationary while i do the suspension work. I was just going to use the 16's to roll the old girl around if I needed to. I just need to get the E90 back on the road first. Yes! I'm a believer! 🙌 So, I contacted them because the site kinda sucks and I was really confused about what I'd need. They put together a package for me and because I was spraying all the seat surfaces and not doing spot fixes I decided not to send them a headrest to colour match, I just used their colour on file (and it was spot on).  I got some heavy duty cleaner, 1L of colour, a small bottle of dye hardener and a small bottle of the dye top coat. I also got a spray gun as I needed a larger nozzle than the gun I had and it was only $40 extra. From memory the total was ~$450 ish. Its not cheap but the result is awesome. They did add repair bits and pieces to the quote originally and the cost came down significantly when I said I didn't need any repair products. I did it over a weekend. The only issues I had were my own; I forgot to mix the hardener into the dye two coats but I had enough dye for 2 more coats with the hardener. I also just used up all the dye because why not and i rushed the last coat which gave me some runs. Thankfully the runs are under the headrests. The gun pattern wasn't great, very round and would have been better if it was a line. It made it a little tricky to get consistent coverage and I think having done the extra coats probably helped conceal any coverage issues. I contacted them again a few months later so I could get our X5 done (who the f**k thought white leather was a good idea for a family car?!) and they said they had some training to do in Sydney and I could get a reduced rate on the leather fix in the X5 if I let them demo their product on our car. So I agreed. When I took Bec in the E39 to pick it up, I showed them the job I'd done in my car and they were all (students included) really impressed. Note that they said the runs I created could be fixed easily at the time with a brush or an air compressor gun. So, now with the two cars done I can absolutely recommend Colourlock.  I'll take pics of both interiors and create a new thread.
