Tachometer wire on 2004 LS Galant

  

unknown_owner -> Tachometer wire on 2004 LS Galant (3/27/2005 10:00:52 PM)

I'm installing a remote starter on my 2004 LS and I can't find the tachometer wire. I have two wire diagrams.

One says it a white wire (AC) located at the Engine speed dectection connector (a single pin connector in the fuse/relay box under the hood).
- I can't find the single pin connector. Would the white wore be below the fuse box?"

The other one says the tachometer is NOT black/white or black (ac) located at "any ignition coil"?
- Can't find the coil. I really don't even see the coil.

Anybody can help me? Any pics would be greatly appreciated.

What does the AC mean anyway?

Well to help those who might need it in the future, I found the tach signal. The new Galants come with multi-coils and they are located on top of each spark plugs. There are 3 wires for every coil, a BLACK, BLACK/WHITE, and a colored one. Use the colored one for a tach signal. Some of the ones I have seen are BLUE/BLACK, PINK/BLACK, and ORANGE/BLUE.

DON'T use the wires on the fuel injectors; they didn't work.

I understand your frustration with that. I had the same problem when I installed a tach in my old car. Except for my car you had to use a series of resistors, or the tach would read 1000-2000 RPMS only.

I beleive that AC actually refers to alternating current. To give a tach signal from a single wire it would need to be alternating. The tach would read the number of ocillations and get the RPMs from that.

could be wrong though
