Tach install

[77fordbornandrasied]

Alrite guys scabbed together all the parts for my park brake so i am finishin that up today and gettin "The Tank" inspected. so my next question is how do you install a tach in these things and as there are a million diff kinds of tachs what one to i buy. ex mech, electric ?

Should only be a matter of 4 wires (3 if you don't have a light hook up). I can't remember the colors of the wires, but one should be a ground, one go to the coil, one to the battery and one for a light source. I've been on a real big Autometer kick lately, but I don't think there is anything wrong with $15 tach you can get from the parts store...I just don't think their tolerances are as tight which leads to variances in actual output.

I can sell you a working vintage tach for $40.00

I have full sweep and side sweep tachs

^^^That's awesome Dennis...any particular brand?


For reference...I did pick up a NIB Autometer traditional chrome 3 5/8" tach on FSB for $25 plus shipping. It retails at just under $150.

Besides these two I also have an 3" autometer

Red is 12v positive
Black is ground
White is to light (if you want)
Green is to negative side of the coil

mil1ion i will get back to you on the tach i am playing with the idea of installing a old GTO hood mount tach ???? anyone ever tried this ??

 

[77fordbornandrasied]

do either of these tachs have a back light and how do they mount???

 

[Mil1ion]

Yes they both illuminate and they mount via the curved mount piece.
