u have to look at ur distributor if it is an HEI "coil on top there is markings on the distributor cap for the tach but if it is a regular distributor with an external coil you hook it up to the neg wire off the coil neg/ black wire
You should hook up the wires for a tach on a 1985 Chevrolet s10 blazer to the negative side of the coil. You should be sure to identify the positive and negative sides of the coil.Ê
how do you hook up a sunpro super tach 2
You would hook to the negative side of the coil. Some HEI distributor caps are marked "tach".
hook your green wire from the tach to the white wire from the coil PAC it should be a white and a yellow wire coming from the coil. the tach should have a white wire that will be your light inside the tach a red wire for power and a black for ground.. good luck
to hook up the tach use the hot lead on the disributor and to any good ground wire and if there is a light hook it to the wire on you light switch
Hello, I found the owners manual for the sun super tach 2 on Sunpro's website. This is the addy. http://www.sunpro.com/publish/2007/09/27/pdf_english_16472.pdf Hope it helps.
if it is a hei ignition there is a place on the distributor cap that says tach.
Should have four wires: Positive, Ground, Light, and Tach. Put ground first! I made this mistake and took out all the lights in my dash. Hook the tach wire up to the male end on the distributor cap (you'll have to route it through the firewall). Hook the positive up to a nearby wire or open spot in your fuse box. I tapped off the radio. Hook the light into your panel instrument light circuit.
Since the coil is in the distributor, simply hook the tach 'trigger' wire to the out put on the side of the distributor cap marked 'tach'.
On the dist., cap, where the wires go in, there is a tab labeled TACH.
Hook it to the negative side of the coil.
green wire on aftermarket tachs are the signal wire i belive
