Ok guys, so I broke my damn stock tachometer and went out and got an after market Autometer tach. I thought I would just wire it to my stock tach wires and that would be it. But Mazda here in Greenville tells me that I have to wire the tach up to my Crankshaft harness. Has anybody ever done this cause "Jeff" told me that there's a 90% chance of blowing some kind of PMC or something like that...I need help HELP ME!!! 99 1.6L Protege LX.

 

sounds like your mazda dealer is trying to lie to you to make you buy parts or services from them.....wow, never woulda thunk a dealer would lie to a customer....

You will need to find an ecu pinout for your specific car (i know nothing of 1.6L engines) Us that pinout to determine your crank trigger wire and splice onto that.

Macdaddyslomo has just done this recently I believe. He may be able to help you further.

 

Check the diagnostic port on the firewall driver side. Purple and white wire is the tach signal. It will also be on the plugs on the cluster if you have a stock tach.This is actually the sam for ALL 3rd gen protege's. However you could have bought a junkyard cluster cheaper than an autometer tach and just plugged it in

 

well the guy that I usually deal with is pretty good to me at MAzda. He gives me pretty good deals on stuff sometimes. but the reason he said it was gonna be a bitch for me was because I have coilpacks not a ignition coil to hook the tach straight up to. So does this mean that I can just plug the tach into the purple and white wire on my stock guage cluster??

 

yes.

 

thanks alot for the help guys, unfortunately I wasn't able to try and do it today cause it's raining down here. We'll see how it goes tomorrow thought rain or shine!

 

It's raining inside your car ??

 

It does that here in SC. It rained in my wife's Galant just the other day.

 

Did Macdaddyslomo recently install a tachometer in his protege? cause now that Jeff from mazda told me theres a chance of blowing somethin, I'm really scared to do it. is there really any reason to be if I'm just tapping the tachometer into the purple and white wire underneath my dash? I feel retarded...

 

I did and it works great. I have had no issues...you Mazda guy is full of sh(izzle)

 

what kind of tach did you hook up? I think the bulb in my tach is bad cause I got it out of a civic used. and when I hooked up the illumination to the illumination wire on my radio, it doesnt do anything.

 

Hooked up a stock tach to a DX. Hook your illumination wire to the green/white wire in your guage harness.

 

macdaddyslomo: You got a "How To" anywhere on swapping a DX cluster for a ES with the white face gauges? I'd like to have a tach as well.

 

easy how-to..purchase ES cluster...run tach signal off diagnostic port from engine port(purple/white wire) to the second to the right top pin(when plugged in) on the middle plug on the cluster..woila!! you have a ach

 

actually Macdaddyslomo. I ran my tach signal off the guage cluster becuse when I plugged it to the purple and white wire underneath my dash the needle of the tach would bob along with the blinking noise of my turn signal...:0P
