Tach install

I'm installing an after market tach and wondering what wire to splive into for my tach signal.
I have an 88 Blazer 4X4 2.8L Auto.
Any help would be great, Thanks in advance.

RE: Tach install

I think its the white wire coming off the coil, but I have a 92 4.3 and thats how I had to hook it up to get the signal.
