130375, Wiring for a tach
Posted by baconater3000, Apr-12-10 05:28 PM
Ok I got this 5 in tach from a friend it has a shift light...I think a black, red, green wire, yellow wire and maybe a few more....Where do I hook this to. I searched and all i was finding is people with the base model and old rs's with no tach....Thanks in advance guys...(remember I give points for good advice).

Look online for the manufacturers directions.
Black and red are pretty self explanatory, green may be illumination. Bottom line is to contact the manufacturer.
Just curious, why do you want a 5" tach?

Tach signal is the only solid white wire in the ECU harness.
Big external tachs with shiftlights are stupid.

But I tried to state that I recieved this tach for free...I was just wondering...I read on a write up somewhere that the white wire is also within the cluster...

Just because you received the tach for free, doesnt mean you have to use it ;)

I'd be inclined to agree. Just because it was free doesn't mean you need to, or have to use it. Unless you're in a full-on race car that goes down the track fast enough that you can't see your tach, its completely unnecessary... And it looks suspect.

Step 1: lookup value of tach new, subtract 40%
Step 2: post tach on craigslist and honduh forums
Step 3: ???
Step 4: Profit.

If you're hellbent on using it... All of these are GENERAL statements, it would behoove you to check the manufacturers' website. As these may not apply to the device you have.
Red - Power, usually
Black - Ground
Yellow - Illum, usually
Green - Tachometer signal
