cant find tac wire

[1986monte]

So today I figured I would wire up the tac. It's a 86 ls Monte
I know it didn't origionally have a tac and it appears its not wired for a tac either there isn't a whitewire like I was told it should


So my question to you. How do I hook it up it has ss guages in it now

Signal wire to tach pin on hei distributor. Power to any key on power source. And a simple ground. Should be purdy easy! Good luck my friend

The Monte SS was equipped from the factory with a tach filter that goes between the tach connection on the distributor, and the back of the tach in the instrument cluster. I don't know if the filter is an absolute necessity, but if the manufacturer put it there, its probably required.

I ran a tach in my 84 Elco that didn't come with one and didn't use the filter. I don't know if its necessary but I never noticed anything wrong with it.

my question is because there is no white wire in the harness for the guage cluster.. so if i were to run a wire from tac on distributer what slot is for the tack on the plug for the guage cluster

It should be located at location 17 on the cluster harness...

complete tach wiring with filter

[1986monte]

I see them from time to time on ebay.

I can have a look I may have an extra here.
